Coding tutorial: Chain-of-responsibility pattern

A peasant, knight and king walk into a software design tutorial, and are here to teach you the chain-of-responsibility pattern. Learn how to create a chain of handlers which can handle different request types.

This tutorial shows you how to code the chain-of-responsibility pattern in the Visual Studio development environment, using a console application and the C++ programming language.

The chain-of-responsibility pattern passes on a request to a chain of handlers one at a time. Each handler can handle different requests. So if the first handler can’t handle the request, then it will pass it on to the next handler. Once a request is handled, the chain ends. Since there is no longer a need to pass on the request.

It is also possible that the request doesn’t get handled by any of the handlers. Since each handler can handle 0, 1 or many requests of different types.

Mastering C++ Programming: A Beginner's Guide to a Powerful Language

In the world of technology, C++ Programming remains one of the most reliable and versatile languages. It has powered everything from operating systems to game development, making it a must-learn for anyone serious about a career in coding. If you’ve ever wondered what makes C++ Programming so popular or how to get started, this guide is here to help.

What is C++ Programming and Why Should You Learn It?

C++ is a general-purpose programming language known for its high performance, efficiency, and versatility. Developed by Bjarne Stroustrup in 1985, C++ builds on the foundation of C by introducing object-oriented programming (OOP) principles, making it both powerful and scalable.

Top Reasons to Learn C++

Wide Applicability: From creating system software to video games, C++ Programming is used across industries.

Job Opportunities: Companies worldwide are always on the lookout for developers skilled in C++ Programming.

Community Support: With a large, active community, it’s easy to find resources, forums, and tutorials to enhance your learning.

Foundation for Advanced Concepts: Mastering C++ Programming lays a strong foundation for other languages like Python, Java, or C#.

Key Features of C++ Programming

1. Object-Oriented Programming (OOP)

OOP principles such as encapsulation, inheritance, and polymorphism make code modular and reusable. For example, creating classes and objects helps in managing larger projects more effectively.

2. High Performance

Unlike interpreted languages, C++ is compiled, ensuring faster execution speeds. This makes it ideal for performance-critical applications like gaming engines and real-time systems.

3. Cross-Platform Compatibility

C++ programs can run on multiple platforms without major modifications, thanks to its compatibility with various compilers like GCC, Clang, and Microsoft Visual C++.

4. Extensive Libraries and Frameworks

C++ offers numerous standard libraries (like STL for data structures) and frameworks (like Qt for GUI development), making it easier to tackle diverse projects.

Getting Started with C++ Programming

Starting with C++ Programming can feel overwhelming, but with the right approach, you can build a strong foundation.

1. Install a Compiler and IDE

You need a compiler like GCC or Microsoft Visual Studio to convert your code into machine language. For a better coding experience, consider using an IDE like:

Code::Blocks

Eclipse CDT

CLion

2. Learn the Basics

Begin with fundamental concepts such as:

Variables and Data Types

Input and Output Streams

Loops (for, while, do-while)

Conditionals (if-else, switch)

Here’s a simple program to print "Hello, World!" in C++:

cpp

Copy code

#include <iostream>

using namespace std;

int main() {

    cout << "Hello, World!" << endl;

    return 0;

}

Popular Applications of C++ Programming

1. Game Development

With its high performance and real-time processing capabilities, C++ Programming is extensively used in creating video games. Frameworks like Unreal Engine rely on C++ for game mechanics and rendering.

2. Operating Systems

Operating systems like Windows, Linux, and macOS utilize C++ for their core functionalities, thanks to its close-to-hardware performance.

3. Embedded Systems

Devices like routers, medical equipment, and automotive systems use C++ due to its ability to manage hardware efficiently.

4. Financial Software

Applications that require fast calculations, such as trading systems, are often written in C++.

Tips for Mastering C++ Programming

1. Practice Regularly

Consistent practice is key. Solve problems on platforms like HackerRank, Codeforces, or LeetCode to build confidence.

2. Explore Open-Source Projects

Contributing to open-source C++ projects on platforms like GitHub can provide hands-on experience and improve your portfolio.

3. Master Standard Template Library (STL)

STL offers pre-built functions for data structures like vectors, maps, and queues, making coding more efficient.

4. Learn Debugging Techniques

Use tools like gdb (GNU Debugger) to identify and fix bugs in your programs effectively.

FAQs About C++ Programming

1. Is C++ Programming Suitable for Beginners?

Yes! While C++ has a steeper learning curve compared to Python, it provides a deeper understanding of memory management and system-level programming.

2. Can I Learn C++ Online?

Absolutely. Platforms like Udemy, Coursera, and Codecademy offer comprehensive C++ courses.

3. How Long Does It Take to Learn C++?

With consistent effort, you can grasp the basics in a few months. Mastery, however, takes years of practice.

Coding tutorial: Observer pattern

The observer pattern has an object named the ‘subject’ which maintains a list of ‘observers’. The subject will notify all the observers when an event occurs. The observers can then choose how they wish to respond to the event.

In this tutorial you will code a zookeeper and animals. The zookeeper represents the subject of the observer pattern. Whilst the animals represent the observers.

The zookeeper will notify the animals when he arrives, and the animals will respond in there own unique way.

To follow along to this tutorial, you can either just read it and apply the knowledge to your programming language. Or you can use Visual Studio, by creating a solution, then create a project with a console application. Then run the project to see the output in the console window.

I think I might be trans, also, any tips for learning how to code?

P.S: I hope you're having a good day/night

How I figured out I was trans was saying a very egg reply to a would you press the button, checking the comments to see if anyone said I was an egg, and then realizing, "hmm, perhaps it may be worthy to look into my gender", and of course I go to Tumblr and after several days of just thinking about it, it hit me like a brick of "holy shit I'm a girl" while I was trying to sleep. And I feel a lot better knowing that I am a girl and I have a place to be one. For learning how to code, the ironic part is that I am not good at it, since I just only did the first tutorial in the series and didn't follow through. I recommend the @freecodecamp.org YouTube channel though, the cpp intro course was 7 hours, but it was worth it
