Why C++ Still Dominates: The Secret Behind Its Power

Introduction

At TCCI (Tririd Computer Coaching Institute), we teach programming languages that have become a heritage. One such language is C, known for its power, efficiency, and versatility. Why C++ Still Dominates The Secret Behind Its Power lies in its ability to provide low-level memory access, high performance, and a strong foundation for other programming languages. Let's explore why C continues to be a dominant force in software development.

The Evolution of C++

C++ was initially designed and created by Bjarne stroustrup in the early 1980s to be an extension of the C language. Over time, it has added modern features keeping backward compatibility intact; thus, it has been a perennial favorite for developers.

Top 9 Reasons Why C++ Continues to Be an Industry Leader:

1. Performance and speed

C++ comprises low-level memory manipulations, hence being faster than most modern languages. This feature explains why it is often used in high-performance applications, including games, finances, and system programming.

2. Versatility and Flexibility

C++ gives the freedom of using multiple program paradigms like procedural and object-oriented, and generic programming. This gives a very good option for programmers to write effective and scalable code.

3. Strong Standard Library

C++ possesses the Standard Template Library (STL), providing a very rich collection of functions and data structures for algorithms to help in faster and efficient development.

4. Cross-Platform Compatibility

C++ code can be compiled, then executed, on various platforms, from Windows to Linux. Therefore, it is a top choice for any software that needs to be portable.

5. Memory Management

C++ includes both features of memory management, manual and automatic, thereby granting the developer more control over the resources which leads to a more optimized and efficient application.

6. Industry Adoption and Legacy Code

C++ is the language for many legacy systems, so rewriting them in a modern language is too expensive and complicated. This alone keeps C++ developers in demand.

7. Major Game Dominator

C++ is the actual language for the largest game engines like Unreal Engine and Unity because of their speed and control to manage the hardware.

8. Embedded Systems and the Internet of Things

C++ is used wherever performance and efficiency are of utmost importance, including embedded systems, robotics, and IoT devices.

9. Competitive Programming

C++ is highly regarded as the best language for competitive coding due to its execution speed and quite superior libraries, hence favored in coding competitions like Codeforces, LeetCode, and HackerRank.

The Future of C++

With periodic updates (like C++20 or C++23 for instance), this language is continuously evolving towards being friendlier and faster for developers.

Conclusion

At TCCI (Tririd Computer Coaching Institute), we regard learning C++ as an important part of training. C++ is always a titan in the programming world, so whether you are a beginner, or a professional programmer, you can open the doors to countless opportunities in futures with this language.

C++ Development on Windows

C++ is the most powerful and popular programming language so far. It is loved by developers because it has less complexity than other languages and also it can be applied to variety of system development scope. C++ has imperative, object-oriented, and generic commands to help developers in general-purpose programming/coding. C++ being an old programming language is still one of the most used languages in the programming world. Because of its huge popularity, a wide range of frameworks has come out on the market to make the developers work on big projects effortlessly. Hence, the frameworks in C++ are increasingly becoming popular. C++ language is mainly used for desktop application development as well as embedded system implementation. However, developing games in C++ language is on the list, though web application in C++ is quite rare. C++ Development on Windows C++ development on Windows has nothing to do with the language; rather it focuses on setting up a development environment/tool chain for Windows. It can be developed for Windows by two common ways i.e.

C++ Development on Windows with Visual Studio

C++ Development on Windows without Visual Studio The developers who work with the Microsoft platform already have a copy of Visual Studio pre-installed. They find themselves in a good situation regarding their projects where they can open any solution, make changes, and compile the file with the idea that all the required files and settings are already configured correctly. But the actual difficulty arises when it’s the time to compile the projects and solutions in an environment which doesn’t have Visual Studio pre-installed. Since they only have to do all the changes manually. However, development with visual studios requires a specific set of IDEs. The best IDEs that will support C++ development on Windows are- i. Visual Studio Code It is an open-source code editor developed by Microsoft. It will provide smart code completion based on the variable types, essential modules as well as function definitions. ii. Eclipse Eclipse is a C++ website development tool. It highlights the syntax you have written and also validates it automatically. It enables you to easily debug the program. It additionally provides readymade code templates. iii. Codelite It is an open-source tool for writing programs in C++. It supports the refactoring of code. It highlights the syntax automatically by giving you the option to customize the syntax color. It can be used on Windows and Mac operating systems. iv. Brackets.io It is an open-source editor for developing web applications using C++. It can highlight the pair of brackets and also allows you to quickly edit the code written. It also facilitates you to customize the UI. iv. Atom It is a simple editor used for writing C++ programs. It can also be customized to do anything without modifying a config file. It can be used for cross-platform editing as well. v. CLion It helps to quickly solve the errors in the program. This IDE facilitates you to analyze the performance of your application without any hassle. It also enables you to test individual units of source code. Setting up C++ Environment on Windows Certain steps are there followed by which you will be able to create a simple C++ Environment on Windows.

Choose a perfect editor Text editor is the first thing that you need to select for your programming. There is no such editor that you can call as the best. There are tons of great editors out there, however, these are some of the recommended ones that are easy and lightweight to use- i.Sublime Text 3 ii.Notepad++ iii.Visual Studio Community

Install a Compiler You don’t have to worry about any compiler if you are already using Visual Studio since it comes with Microsoft Visual C++ compiler. But if not, then you will need additional compiler installed in your systems such as GNU Compiler Collection or MinGW-w64. However, MinGW-w64 is exclusively used by Notepad++ and Sublime Text.

Set up your editor Sublime Text and Notepad++ are very easy to be configured with the MinGW-w64 compiler. An in-built system already exists in Sublime Text. But that builder doesn’t fit properly with MinGW. Hence, a new build file that will use the MinGW-w64 compiler has to be created. In the case of Notepad, there is no such in-built system so, a standard NppExec plugin can be used to run arbitrary commands.

Write Code It is the final step of the setup process. It is completely up to the developer. However, Sublime Text and Notepad++ are quite more lightweight as compared to Visual Studio, so, those who are willing for something simpler or lighter on the system resources, and then they can choose any of it. C++ GUI Development Certain cross-platform GUIs are there for C++ that is used in C++ development purposes. C++ doesn’t come up with a built-in graphical front-end like Python and many other programming languages. However, graphics on each operating system are created in a very different way to facilitate you to optimize all required functions. Such tool kits are- Qt It is the most popular and massively used open-source tool that is used in C++ GUI development. Its biggest strength is the windowing system, through which you can create user interfaces. It also includes advanced features such as displaying charts, data visualizations, and maps from third-party providers making it easier for the users to operate and use. wxWidgets It’s quite similar to Qt in many ways. Some developers prefer it because wxWidgets use native SDKs that mean Windows built-in routines on Windows only and Mac routines on Mac to draw graphics. It makes the applications look more native on Windows as well as on Mac because of the graphics. JUCE It is an open-source cross-platform library that also has a similar license to that of Qt. It focuses on audio, interactive, embedded, or graphic applications for C++ development on Windows. It also includes many user-interface elements, graphics, audio, networking, cryptography, multi-threading, integrated interpreter, etc. for better flexibility and performance. CEF It can be abbreviated as “Chromium Embedded Framework” which is a simple framework for embedding Chromium-based browsers in other applications. This is why it is different from the other C++ libraries which are used for creating standalone applications. CEGUI It works on Windows, Mac, and Linux supported by 32- as well as 64-bit. The primary focus of this GUI tool is on game development. Apart from this, it provides the developers a bunch of Widgets i.e. buttons, Combo, etc. so that you won’t be restricted to just game applications. Most games mainly require a GUI for the menus and configuration screens such as DirectX or OpenGL. OdiTek’s C++ Services Offerings Full-cycle C, C++ software development services from Oditek are tailored to specific requirements. Whether you are looking to develop, upgrade, modernize or support and maintain C, C++ based applications and product solutions, OdiTek’s development team has over 15 years of experience to efficiently assist you no matter what environments or development platforms you are using.

Conclusion C++ programming language is mostly used for desktop application development and embedded system implementation. But Apart from this, C++ application plays a vital role in gaming application development including GUI. Most people think that C++development Windows is a complex task because of the complications in choosing the editors, compilers, IDEs, GUIs, etc. However, it depends upon the analytical skills of the developer that how and what tool he will choose out of the large options to perfectly fit into the pre-determined goal. Oditek Solutions deals with implementing a wide range of IDEs as well as GUI toolkits for C++ development on Windows. We, at Oditek, have expert developers who can help you resolve all your confusion regarding identifying the suitable IDEs and GUI toolkits as well as implementing those over your preferred application development.

Project Updates - 5/7/24

Looks like it's time for my bi-yearly "remember this blog exists and post an update"! 😄It's been another few months of off and on work due to my day job and other life things going on, but still trying to chip away at things.

More on the individual projects under the cut~

libtcod tutorials

Since my first crack at writing up the C++ tutorials for libtcod, I've mostly been trying to decide what I want to show for them. Part of the feedback I received on the first tutorial was that it didn't have a clear audience, whether it was for beginners to programming or to more advanced developers. I've gone back and forth on this, and I think I've settled on making it more accessible to newer programmers, though that does mean I have some reworking to do. On the upside, I was able to fairly easily change the code on the early tutorials to account for newer versions of libtcod.

I have also been working through reimplementing later tutorials. Most recently worked on the fourth tutorial, where I decided to introduce an event handling system using double dispatch (specifically using the way outlined in this blog post). This approach is a bit complex to implement and describe since it uses certain template patterns, but overall it should allow for the rest of the tutorials to easily add functionality by simply adding events and new event handlers. Actually implementing it took a couple of days of trial and error due to a lot of factors (mostly trying to understand how it all worked myself), but now it's in a good state and pretty easily extendable! Explaining it in the tutorial, however, will be a different story 😅

OpenHomeworld

This is mostly still in the rough design phase still. Most of the tinkering I've done has been around loading and listing the Bigfile contents, and optimizations around that. I'm tempted to start working on a GUI archive tool to display items as well as insert and extract files from the Bigfile, though I'm not sure if I want to make something in Qt or try my hand at making a plugin for Godot. The Qt tool would probably end up being pretty simple and just show a list of files like how 7zip or WinRAR work, which itself would be just a UI around a command line tool, really. If I tried creating a Godot plugin, I'd also want to handle viewing and editing the files extracted from the Bigfile, too, and that would probably also require implementing the way to handle the Homeworld texture, mesh, script, and other files that have their own format internally. The Godot option is tempting, since I would want to have some sort of editor for the project at some point, but I'll probably keep is simple at this point and just make some small command line utilities. Options, though!

At the same time, I've been playing with the source port of the original game and trying my hand at updating the build system to CMake. This has gone mostly smoothly, except for one snag that I have yet to figure out a good way to handle. You see, the old Homeworld source code is written in C, but the game levels were created in a scripting language that the Relic devs used called KAS (which I think stands for Kick-Ass Scripts lol). Essentially these KAS files would get converted into C code and compiled into the main game executable, and the way the game is built with Makefiles makes it pretty easy to hook in calls to the utility programs to convert these files. In all my messing around, though, I have not been able to successfully replicate that process using CMake. I might need to specify all of the mission files explicitly to have them build and link properly, but I worry I'll end up running into a situation where the build will fail due to things being run out of order in multi-threaded builds (which is already a problem with the source port process though). Analysis continues...

Metal Max Redux - GBC game project

In my last devlog, I mentioned that I was interested in making a game based on a series of obscure JRPGs. The Metal Max/Metal Saga games are ones that I found last year and fell in love with, so much so that I wanted to create a game based off them. The first game in the series was an NES game that was never released in North America, but has a wonderful fan translation patch that I was playing through, but have not actually completed quite yet. It's a fun little RPG where you can drive tanks around a post-apocalyptic world fighting monsters, and has a pretty open structure to it, not unlike the first Dragon Quest or Final Fantasy.

Last year I also came across GB Studio, a free and open source all-included editor for creating GameBoy and GameBoy Color games from scratch, and this gave me a great idea: since I was a huge fan of the GBC port of Dragon Quest I+II, I thought I would make a similar port of Metal Max. So Metal Max Redux was born!

I'm still mostly in the beginning stages with this project still, but I've created a basic mock-up of overworld movement and triggering random battles. The random battle system took a while to puzzle out, and at one point I thought I was going to have to extend the engine that GB Studio uses, but I was able to make it work using a step counter attached to an invisible player object that seems to work well enough. Next steps will probably be analyzing how the NES battle code worked, so I'll be looking at lots of assembly. Fun times! 😄

Free City-States - lewd city management game

Finally, a project to earn my screenname 😄 I really enjoy city builder and management games like the Caesar series and Dwarf Fortress, and within the last few years games like Crusader Kings and Stellaris.

A while back, I was starting to help out with a project called Free Cities Reborn, itself a reimagining of an HTML game called Free Cities, a lewd management game with some city building aspects. I couldn't continue with FCR after a while due to some growing reservations about the content and focus of the game which extends somewhat to the original too, since its core gameplay is around the raising, training, and sale of sex slaves. It's a fun indulgence, if somewhat of a guilty pleasure, and it's certainly not the first game that's concerned with the subject matter, but I still felt weird contributing to a project where it was so focused on that. But at the same time I started to think about creating my own spin on the core ideas, and creating my own lewd game in general.

So that's how Free City-States came to be envisioned. The core game concept in my mind is more akin to Crusader Kings and Stellaris than to Caesar and Dwarf Fortress, but focused on the management of a fantasy city-state. I've created a small mock-up in Godot as my first real foray into that game engine so far, and hoping to continue chipping away at it as the concept becomes more fleshed out 😊

Wow, this ended up way longer than I thought it would, and this doesn't even cover all the small ideas and tinkerings I've been working on! Putting it down into words, I guess I really did do a lot between the last post and this one 😅 Hopefully future posts will be a little shorter, but this was a fun way to reflect on the things that I'm working on. I think I'll try to make fortnightly updates if I can, going forward.

Reduce Testing Efforts 

There is no need to employ a developer in order to test application performance on two separate platforms when you are building an application using flutter. You spend less time testing because the QA programmers only need to test one version of the application. 

In order to make sure that the application is working smoothly on every platform and there are no technical glitches, you have to contact the professionals as they are well-trained and experienced in building a functional and easy-to-use application. 

Now you have an idea why you should hire Flutter app developers or partner with a trusted Flutter app development company for a mobile app development project. 

The Last Note 

If are you interested in building a mobile application using the Flutter framework, you made the right choice. Flutter is the better choice for successful app development. However, creating the application from scratch is a difficult undertaking. You have to hire dedicated developers in USA as they have a good portfolio to work on this technology. 

Moreover, the experts ensure the quality of the project while building the Flutter application. This is why you have to consult with the professionals who help you in every possible way to build a functional Flutter application.

LearnXinYMinutes is a really good reference if you already have some sense of how things are put together, some languages don't require a CS degree to read through the explanation. I even used it myself to quickly review C# since I have barely touched that language in a few years (Elixir, Python, C, Bash, Pascal-like -- are what I use in my day-job).

https://learnxinyminutes.com/docs/csharp/

@oneominousvalbatross Jump to "Bicycle" for the visibility (public, private, protected, internal) explanation with Ctrl+F to search.

Microsoft's docs on it are also an *okay* reference, there was a lot in the .NET implementation that I ran into as issues for dealing with raw network and serial connections, it's still documentation.

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/accessibility-levels

There's some foundations that need to be found outside of tutorials, here is a summary of a 100 level Computer Science course. C# is going to fall into the realm of OOP (Object Oriented Programming); where rather than writing functions that just do stuff, that stuff is attached to classes as methods. Other stuff that is stored as variables of the class is what are known as properties of a class or object. There is a distinction between class and object, where the class is typically called the blueprint or template; this is a half-truth and a little more complex without getting into how programming languages are designed. The class can contain methods that act on the instance of the class (the object), or methods that act on data fed to a the class itself when they are declared with "static".

FooClass foo = new FooClass(); // Object

foo.someSelfOperation(); // Instance method

FooClass.turnXintoY(bar); // static Class method

// public static turnXintoY(int x) { return y; }

This is where I explain visibilty/public/private.

Public: Any class/object can access the labeled property or method. This can be anything that references it.

Private: Only the class/object itself can access the labeled property or method.

Protected: Only the class/object itself _and_ those that *inherit* it will have access. I recommend reading up on Inheritance early it really helps with code reuse.

// Has Access to protected in Bicycle

class MountainBike : Bicycle { ... }

// Can only access public in Bicycle

class FooBar2000 : MusicProgram { ... }

Internal: Only files in the same Assembly will have access. What does that mean? Files that get compiled into the same final file will have access, like `exe` and `dll`. It doesn't matter so much if you're not building libraries for other people to use, but if you build two projects the `exe` will not be able to access those protected items in the `dll`. `pingle.dll` will similarly not be able to access protected items in `sprocket.dll` if it is linked against it. Really, you might not have to worry about this one until much later.

That's it for what I can provide right now, don't look into C# as C-like because then terminology will get mixed; `static` means something **completely** different in C.

Hi! I'm learning C# right now, and the tutorials I'm using are great, but as a coding expert, I was wondering if you had any off-the-cuff recommendations for like, basic C-language coding terminology explanations. Like, I *sort of* get the public variable distinction, but I don't *really* get it and I'd love to be able to read an explanation for things like that specifically.

Sorry, I'm not really sure where you'd go for that sort of information. Any followers have any advice?

Java for Kids

Coding is a crucial talent that is progressively becoming ubiquitous and vital in our lives as the world becomes more dependent on technology. Today, knowing how to code is a highly sought-after ability that businesses are looking for. Coding is the process of laying out a set of instructions for a computer to follow in order to teach it to perform a specific activity. Almost all of our technology uses coding, which can be done in a variety of languages like Scratch for basic coding, C++ for building and creating entertainment applications, Java, JavaScript, and Python for intermediate and advanced coding.

What is Java?

Java is a programming language that is extremely popular in the coding world. Out of 700 languages,Java is frequently ranked among the top ten most used languages. But why is Java so very popular? And why is it a suitable coding language for kids to learn? Well, continue reading to find out more.

Created by James Gosling, Java is now used by many big companies such as Netflix, Meta, Airbnb, Microsoft, Spotify and Amazon. Java is also used in many industries such as cybersecurity, video games, cloud computing and e-commerce. Thus, learning how to code in Java is an important skill and is valuable for numerous professions.

But why is Java so popular? Well, unlike other coding languages such as C++, which uses structured programming, which involves repeatedly using chunks of similar code over and over again, Java is an object oriented programming language, which involves basic instruction-containing classes and objects and a class is a type of template. An object can be easily inserted into the code by a programmer. There is no need to create code to make the object function because it inherits its behaviour from the class it belongs to (its template) and it is immediately usable.

Advantages of Java

Because it is durable, Java is a wonderful language for kids to learn. It has existed since the beginning of the 1990s. In the realm of computers, that's a long period of time. Additionally, Java has a sizable development community of roughly 9 million people and a significant online presence. Numerous sophisticated apps are powered by Java, and the language is here to stay.

Learning Java improves children's soft skills and increases perseverance. Java programming fosters both strong abstract reasoning abilities and inventiveness. A problem can frequently be approached and solved in a number of different ways. Finally, cooperation skills are developed by aspiring programmers through group classes and projects. Professional software engineers frequently collaborate in teams to plan projects, produce code, review work, and resolve issues. Hence, Java is an ideal coding language for kids to learn. The best candidates for learning Java, an intermediate language, are those who want to design and build their own apps. Java is famous for its adaptability and ability to generate a wide range of applications, which broadens students' coding options.

How to learn Java

There are many ways to learn Java, some of which are listed down below.

A discussion of the more complicated aspects of the C# language

What you’ll learn

Advanced Topics in C#

Apply sophisticated C# solutions to problems

Explore different programming styles and approaches

Requirements

Deep knowledge of the C# programming language

Familiarity with key .NET data structures and algorithms

Good command of modern IDEs and developer tools

Description

This course presents a collection of interesting/unusual case studies where C# is used to solve a particular problem. This course is 100% practical and demonstrates mainly the practical applications of C# in building solutions to common problems.

The main themes covered in this course are:

Numerics — the specifics of how to work with numeric types in .NET, with a focus on SIMD data types and operations.

Reflection — how to operate reflection mechanisms to investigate assemblies and types, how to create types and invoke their members. Also a look at the practical use of reflection for working with attributes.

Memory Management — a discussion of the latest C# features for high-performance computation, such as the passing of value types by reference, ref structs, and Span<T>.

Extension Methods — a seemingly simple mechanism that has plenty of advanced uses.

In addition, this course comes with a section dedicated to assorted topics that also showcase advanced uses of C#. These topics include:

Exploiting IDisposable — shows how you can abuse the IDisposable/using mechanism in order to dynamically define operations as pairs of start/end calls. Useful for things like simple performance measurement.

Continuation Passing Style — demonstrates how you can define complex algorithms in terms of sequentially invoked methods with customized return types indicating the result of the operation.

Local Inversion of Control shows that sometimes inversion of control happens at a local scale. Here we use extension methods to invert control on a bunch of different data types, providing useful functionality.

Beyond the Maybe Monad — even though C# introduced the ?. operator in order to chain null checks together, the classic monad implementation, based on extension methods, is still relevant, as it can also handle other scenarios.

Mnemonics — not so much a C# language feature but rather an interesting way of defining huge sets of similar code templates that can be expanded quickly to the code constructs you need the most.

Course Pre-Requisites

Good understanding of C#

Understanding of object-oriented programming (OOP)

Experience writing real-world C# applications

Why Ionic Hybrid network becoming more popular day by day

Introduction of Ionic Framework

Ionic is a complete open-source SDK for hybrid mobile app development created by Max Lynch, Ben Sperry and Adam Bradley of Drifty Co. in 2013. Ionic is world’s most popular cross platform mobile development technology. Basically it’s hybrid mobile app development framework. Using Apache Cordova, it can be easily run on mobiles. A big advantage of using Ionic is that the code base remains the same for all mobile platforms and the UI/UX looks like a native mobile platform. The good news is: if you can manage to create websites, you already know how to build mobile apps. Ionic Framework offers the best web and native app components for building highly interactive native and progressive web apps. It is the only mobile app stack which allows developers to design apps for all app stores and the mobile web, using an unique code base. Moreover, Ionic’s Platform Continuity guarantees your app will look superb on every single device. Ionic provides tools and services for developing hybrid mobile apps using Web technologies like CSS, HTML5, and Sass. Apps can be built with these Web technologies and then distributed through native app stores to be installed on devices by leveraging Cordova.

Benefits of Ionic Framework

Platform Independent Framework- Ionic can recognize the platform specific advanced CSS proportional to the native look and feel on different mobile operating systems. It reduces the requirement for code changing as it gives the codes of mobile-optimized HTML, JS, and CSS components. Apart from this, ionic integrates into Angular JS which becomes a robust structure making code excellent as well as more manageable. This empowers the Start-up entrepreneurs to come out with newer concepts at reduced budget.

Cross-Platform Mobile App Development with Ionic- Building an application without a moment's delay is essential, and it should be compatible with all mobile devices. However, it needs extremely limited use of time, assets and efforts, and helps in giving a unified look and feel. Besides, Ionic helps with building applications quickly and with expertise, and deploys standard tools with a solitary code base.

Default User Interface- Ionic has many default CSS and JS parts that cover the vast majority of the basic things you need to make a mobile application. . Apart from regular ones like buttons and navigation it also includes form inputs, lists, cards, sliding boxes and many more. These can be easily customized by adding CSS classes to the element. The default styles are basic, smooth, and you can without a doubt redo them by adding pre-defined CSS classes to the component.

Based on AngularJS- If you’ve worked upon Ionic, and then you would likely realize that it is developed on top of the Angular JS framework. The extensions to HTML's sentence structure offered by AngularJS are extremely useful for mobile app designers. The Ionic structure utilizes AngularJS to offer a bunch of center functionalities to the designer with the goal that they can incorporate alluring components into the application.  AngularJS is an ideal approach to make program based applications, while with the assistance of the Ionic structure, versatile designers can make hybrid applications and web applications.

Utilizes Cordova Plugins- Plugins play an essential part in Ionic application development. Modules are coded in JavaScript and come appended to the application. Ionic framework application development utilizes Cordova plugins to help designers in accessing different components of the versatile framework- for example, camera, GPS, and so on. According to your business and offered administrations, mobile app developers can utilize any of these modules to build their ideal mobile application.

There are a few good reasons to go with Ionic, depending on what you would be using it for:

1. Ionic use Angular’s MV* paradigm: If you are a web developer and want to be able to compete in the mobile space Ionic is great for you. Ionic uses HTML and CSS to lay out its views, so not only will you have all of the power of CSS transitions and canvas drawing, but you will also feel at home with the DOM. If you’ve ever used Angular in production, this will be doubly true for you, because the logic layers of Ionic use Angular’s MV* paradigm.

2.Desktop support: Ionic has added a flexible grid, and split-pane type features, allowing you to build mobile-first apps with responsive desktop layouts.

3.Open Web Standards: To paraphrase one of their founders, you’re betting on the open web, rather than getting stuck learning single-platform technologies that don’t carry over. (e.g. Learning CSS and DOM layouts versus Xcode’s autolayout)

4.Progressive Web Apps: This is a big trend on Google and Ionic’s radar, and it seems like Ionic is uniquely positioned to let you build app-class web experiences that can also be published in the App Store.

5.If you are bootstrapping a start-up and want to cut development time and cost by leveraging existing skill sets, Ionic is one of the best choices. Ionic creates apps for iOS, Android and Windows. It has default CSS that changes between versions for a Native experience. And all this can be done in JavaScript which is one of the most common programming languages known by developers now because of its ubiquity on the web. There are other frameworks around now that can achieve this in different languages, but most of them are not as popular or have as much support. So unless you have a specific reason you need to use python, Ruby, C++, Java etc. stick with Ionic or React Native in JavaScript or Xamarin in C#. Those are the most mature communities for cross-platform apps.

6. If you are new to web/mobile development the skills you will learn making things with Ionic will take you a lot further than what you will get with native. JavaScript is everywhere. It is more popular than Swift, and more importantly, it can be used for a lot more things. Java is really popular as well, but in my opinion, JavaScript seems to be slowly taking over Java’s position in the web development world. Companies that were built on java will stick around for a long time, but many new ones are being built on stuff like JavaScript, Ruby, Go and the like. And yes that list will be different in a few years, but Java will not be making it back on, and JavaScript will be the longest lasting one that is around for now.

7.Ionic Community: There’s a community of over 30,000 members on the Ionic forum, an active Slack Channel, and Ionic is the 45th or so most popular/starred repo on Github.

How to Install Ionic Framework

Make sure you have an up-to-date version of Node.js installed on your machine. If you don't have Node.js installed.

Open the command prompt and verify the Node.js version by using the command node -v.

To install Cordova and Ionic, use - npm install -g cordova ionic.

Make sure to install the latest version of JDK and Android Studio IDE for Android development.

To create a new project, use - ionic start projectname template.

Inside the project folder, you can add Android/iOS platform based on your development using the command - ionic cordova platform add android.

After these code changes are done, you can generate the required .apk file with the command - ionic cordova build android.

Once the .apk file is generated successfully, you deploy the file on a real device and do the testing, or you can test it as a web application using a browser.

To run it in a browser, use - ionic serve.

To run it on a device, use - ionic Cordova run android -device.

Finally, play with Ionic!

Teaching Inheritance

by Dan Roberts, Lead Instructor

Not one of them is like another. Don't ask us why. Go ask your mother. -- Dr. Seuss

Think back to when you were learning your first object-oriented programming language. If you learned to program in the last 15 years, there's a good chance that was your first language, period. You probably started off with simple concepts like conditionals and loops, moved on to methods, and then to classes. And then at some point your instructor (or mentor or tutorial video) introduced a concept called inheritance.

If you're like me, your first exposure to inheritance was a bit of a mess. Maybe you couldn't quite get a handle on the syntax. Or maybe you were able to make it work on the class project and pass the exam, but couldn't quite figure out where you would ever use this in the real world. And then once that introductory course was over, you probably packed inheritance back up into your mental toolbox and didn't use it again for a long time.

The fact is, inheritance is complicated. It's hard to use correctly, even for experienced engineers - it took me several years in industry before I felt like I had a good handle on the subject. Yet inheritance is a tool with first-class support in most modern languages, and which is taught to many novice programmers almost immediately.

In this blog post I'll dive into why teaching inheritance is hard, some of the problems with current methods, and what Ada Developers Academy is doing to try and address this problem.

Do We Need Inheritance?

The first question we should ask is, "do we really need to teach inheritance?" This might seem like a silly question - everyone teaches inheritance, it's a key part of object-oriented programming! However time is a scarce resource in a program like Ada's, and everything we do teach means there's something else we don't teach. We've found more often than you might expect that we can drop something that "everyone" does, and end up with a leaner curriculum that is more valuable to both our students and their employers.

But as it turns out, we do need to teach inheritance. This is due to the way we leverage frameworks like Ruby on Rails and ReactJS later in the course. Both Rails and React use inheritance at a fundamental level, and our curriculum wouldn't make sense without it. Moreover, inheritance is an important technique for building real-world software, and our graduates use it on a regular basis in the wild.

Whether inheritance should be taught to novices who don't have an immediate need for it, for example in the first year of a 4-year university program in CS, is a different question. It's also not a problem I'm being paid to solve / write a blog post about. We know that the curriculum we cover at Ada does need inheritance, so we can confidently move forward with our analysis.

What it Means to Teach Inheritance

I have heard using inheritance when writing software compared to using a lathe as a craftsperson. Both solve a certain class of problem extremely well, and neither is particularly useful if you don't have that problem. Both lathes and inheritance take a fair bit of training to use well, and both are liable to make a big mess if used incorrectly. Every machine shop has a lathe, and most modern programming languages support inheritance.

The lathe metaphor allows us to break down the problem a little more. Thinking about it this way, we can see that any curriculum on inheritance needs to address two types of questions.

How do you use inheritance? What specific syntax do you need, and how does that change the way information flows through your program? What rules do you need to keep in mind as you work (e.g. Liskov substitution, the open-closed principle)? These questions are more mechanical, and the answers are often language-specific.

When should you use inheritance? How do you identify that a problem is likely to be neatly solved by inheritance, or that inheritance is a poor choice? What are the tradeoffs involved in deciding whether or not to use inheritance? These questions are more theoretical, and the answers are likely to apply no matter what language or framework you use.

Thinking about these questions leads us to two main issues that make teaching inheritance difficult:

The syntax and semantics of inheritance are tricky

Problems that are well-suited to inheritance are complex

Let's dive into each of these a little deeper.

Programming with Inheritance is Tricky

One of the main reasons teaching inheritance is hard is because inheritance itself is hard. At a high level inheritance is easy to explain: one class gets all the code from another class, and can override pieces and add its own bits. As so often happens, the devil is in the details.

For example, with Ruby the following questions arise:

Are static methods inherited? Can they be overridden?

How are instance variables, class variables, and class-instance variables handled?

Can constants be overridden? If not, what should you do instead?

How does inheritance interact with nested classes?

What has precedence, methods from the parent class or from a mixin?

And that's for Ruby, which is supposed to be beginner friendly! Other languages have their own wildcards:

Python: multiple inheritance

JavaScript: prototypical inheritance model, multiple types of functions

Java: static typing and explicit polymorphism, interfaces, templating

C++: all the Java problems plus memory management and object slicing (shudder)

Whatever language you choose, there's going to be a lot of rules to remember. How do you encode all these, especially for a novice? How do you decide what to include up-front, what to put in the appendix, what to omit entirely? How do you introduce specific details while still keeping the discussion general enough to translate to other languages? This is an important part of the problem - all your theoretical knowledge of how inheritance is used and what kinds of problems it solves won't do you any good if you can't apply it in code.

Fortunately, this part of the problem of teaching inheritance is well-understood. There are many excellent texts that round up the complicated syntax and semantics of inheritance into digestible, intuitive chunks. Any alternative treatment of inheritance needs to acknowledge this challenge and build upon this existing work.

Problems that Need Inheritance are Complex

The other reason that teaching inheritance is hard is because problems that benefit from inheritance tend to be complex. At a minimum, a problem to be solved with inheritance needs:

Two or more domain objects that are similar enough they need to share code, but not so similar that they could be combined into one class

Enough other things going on that it's worth encapsulating the domain objects as classes in the first place

That's a non-trivial amount of complexity, especially for a classroom full of beginners. How can you reasonably build a school project that establishes this complexity, but still fits within the tight time limits of the course? This is where existing curriculums tend to break down.

One tool that springs to mind to address this challenge is scaffolding, possibly by implementing some portion of a project in advance. This allows an instructor to reduce the complexity of the work required of the student, without reducing the complexity of the problem space as a whole. Deciding exactly what and how much to scaffold requires us to do a little more research, so we'll come back to this problem later.

How is Inheritance Used?

Since Ada is a workforce development program, one of the most valuable things we can do is ask "what's going on in industry?" Specifically,

How is inheritance used in the real world?

How is inheritance most likely to be used by a junior engineer in their first year or so on the job?

Understanding how inheritance is used can give us some direction on how it should be taught. Let's look at a few examples.

Rails

In Rails, almost every class you write will inherit from something. The two most common are

ActiveRecord::Base for models

ActionController::Base for controllers

You also see inheritance used for everything from database migrations to configuration management - its the Rails Way™. If you want to do something, you inherit from a class somewhere in the Rails framework. These superclasses are generally quite abstract, and each covers some functionality specific to the domain of an MVC framework.

Another important idiom is the template method pattern, as made famous in the Gang of Four book. A great example of this is with database migrations, where you define an class that inherits from ActiveRecord::Migration and implement the change method, and Rails takes care of the rest. Controller actions also mimic the template method pattern, particularly if your application uses the builtin tools for RESTful routing.

For the most part, Rails does not have you define your own superclasses. The exception to this is ApplicationRecord and ApplicationController, which sit in the hierarchy between concrete models or controllers and the abstract Rails implementation - these are generated automatically by Rails, but are open for you to modify.

React

React isn't quite as broad in its use of inheritance as Rails. However, every component class inherits from React.Component.

In React we again see the template method pattern pop up. Whether you're implementing render or componentDidMount, React knows the algorithm and you fill in the details.

React also does not encourage defining your own superclasses. In fact, their official documentation is rather explicit that inheritance between components should be avoided.

Other Frameworks

Rails and React are the two industry-grade frameworks I'm most familiar with, but I've dabbled in some others, namely Android (Java) and Unity (C#).

Android follows a similar pattern: everything you write inherits from some builtin class, template methods abound, and developers are discouraged from building their own inheritance relationships.

Unity matches the pattern as well, but they seem to be more lenient about extending your own classes, at least as far as I can tell from the Unity documentation on inheritance.

Industry Experience

This matches my experience of how engineering work tends to be done. Design work, in this case identifying the abstraction and building the superclass, is done by the team as a whole or by someone with an impressive sounding job title like "principal consulting systems architect". Implementing the details in a subclass is the job of an individual engineer.

Concretely, as I was spinning up at Isilon I spent a lot of time working on C++ and Python classes that filled in the details of an existing pattern, and not a lot of time inventing new patterns. Template methods were something I used frequently without having a name for them, and which I later wished I had learned about in college.

Summary

Setting Use case Write subclasses Write superclasses Abstract classes Template methods Rails Web servers ✅ ❌ ✅ ✅ React Single-page applications ✅ ❌ ✅ ✅ Android Mobile apps ✅ ❌ ✅ ✅ Unity Video games ✅ ✅ ✅ ✅ First year in industry Any or none of the above ✅ ❓ ✅ ✅

There are a few clear takeaways from this quick survey:

Inheritance solves a complex problem. Programs that benefit from inheritance tend to be fairly large

Writing a subclass is much more common than writing a superclass

Often the superclass is provided for you by whatever framework you're using

Superclasses tend to be abstract, both semantically (embodying a high-level concept) and functionally (never instantiated)

The template method pattern is extremely important

Existing Work

We've built an understanding of what a new engineer needs from an introduction to inheritance. How well does existing computer science curriculum match up with this?

Building Java Programs

We'll use a case study to demonstrate: the excellent Building Java Programs: A Back to Basics Approach by Stuart Reges and Marty Stepp. This text is used by many introductory CS courses, including the University of Washington, as well as by AP CS classrooms supported by the TEALS program. My first exposure to the book was while teaching with TEALS back in 2014.

Building Java Programs does an great job introducing the vocabulary and syntax of inheritance.

The first example is different types of employees in an HR system. This is simple enough to demonstrate syntax while still somewhat plausible - not an easy balance to strike.

The text includes a discussion of where inheritance is not appropriate, and the difference between is-a and has-a relationships.

The chapter introduces interfaces, abstract classes and abstract methods, and the ability to override a method. However, it makes no mention of the template method pattern.

The chapter finishes with a more complex example dealing with different types of stocks and assets.

This is substantial enough that inheritance is an appropriate technique.

In this example, the pieces at the top of the hierarchy are abstract (an interface and an abstract class), matching the pattern identified above.

The book does not provide any context for how this code will be used. I would argue this is a major oversight. Writing code in a vacuum is fine for experienced engineers, but in my experience novices benefit from concrete examples of how code will be used from the "outside". With inheritance in particular, this would demonstrate how polymorphism is useful.

There is no mention of the idea of extending a class implemented by a framework.

In general Building Java Programs is excellent, and I have a tremendous amount of respect for Reges and Stepp. It certainly did a good job of preparing my students for the AP CS exam. However, it does not introduce inheritance as it is used in the real world, particularly by novice engineers. As far as I can tell this is typical of introductory CS courses - certainly my undergraduate education at Purdue followed a similar pattern.

Design Textbooks

There is another type of text that addresses inheritance: books on software design. Famous resources like Practical Object-Oriented Design: An Agile Primer Using Ruby (POODR) by Sandi Metz, or Design Patterns (the "Gang of Four" book) by Gamma, Helm, Johnson and Vlissides address software design more generally, employing inheritance as one tool among many.

However, these books are targeted at experienced engineers trying to up their game, not at novices learning their chosen language for the first time. Moreover they discuss design from a ground-up perspective, whereas an engineer beginning their career is likely to build on the shoulders of giants, extending existing designs rather than inventing new ones.

An ideal curriculum would bridge the gap between these two approaches, introducing both syntax and common inheritance idioms, and getting new engineers used to the work of extending an existing class.

Ada's Approach to Inheritance

The instructional team at Ada has been unhappy with our approach to inheritance for a while now, but we haven't quite known what to do about it. Now that we've done some research and formalized our engineering and pedagogical intuition, here's the approach we've come up with:

Simple examples and accessible metaphors are fine for introducing syntax and semantics, though as Reges and Stepp demonstrate they don't have to be completely unrealistic.

Common idioms like abstract classes and the template method pattern should be introduced as soon as the basic syntax is understood.

Students' first serious inheritance project should involve extending an existing superclass.

This matches the way inheritance is used in the real world, and makes the benefits (not having to re-write a bunch of code) immediately clear.

Instructors would provide the following scaffolding:

Superclass implementation

Driver code demonstrating polymorphism

Another subclass, to model the inheritance mechanism

Possibly a test suite or test stubs

If time permits, a second inheritance project would focus on design, and have students build both the superclass and subclasses, as well as driver code.

At Ada, the first inheritance project takes the form of OO Ride Share. Students are asked to load information about drivers, passengers and trips from CSV files; we provide a CsvRecord superclass and Passenger and Trip subclasses pre-built. We feel this problem is complex enough to justify inheritance but simple enough to spin up on quickly. It also mimics the way ActiveRecord is used in Rails, which will hopefully lead to more comfort and deeper understanding once we get into our Rails unit.

The second project is still in the planning phase, but the idea is a command-line app that integrates with the Slack API. After an in-class design activity students will implement a Recipient superclass that handles most of the API interaction, and User and Channel subclasses that fill in the details. They will also build a command loop that interacts with the user, demonstrating the power of polymorphism. We don't have the project write-up finished yet, but there is a prototype of the end product.

We've spent a lot of time thinking about this fresh approach to teaching inheritance, and I'm excited to see the results. Watch this space for an update in a couple months as we conclude our Intro to Ruby unit and move into Rails.
