User Defined Function In C Programming: 

In the realm of C programming, efficiency and organization are paramount. One of the key tools that C programmers employ to achieve these goals is the concept of User Defined Functions (UDFs). These functions serve as the building blocks of a C program, allowing developers to modularize their code and enhance its readability. In this article, we'll delve into the world of User Defined Functions in C Programming, exploring their significance, structure, and practical applications.

1. Understanding Functions in C

Before delving into User Defined Functions, it's essential to grasp the concept of functions in C. In C programming, a function is a self-contained block of code designed to perform a specific task. Functions are essential for breaking down complex programs into manageable segments.

2. What are User Defined Functions (UDFs)?

User Defined Functions, as the name suggests, are functions that C programmers create themselves to meet specific requirements. Unlike built-in functions, which come with the C library, UDFs are tailored to the unique needs of a program.

3. The Anatomy of a User Defined Function

Function Prototype

A UDF starts with a function prototype, which includes the function's name, return type, and parameters. This declaration informs the compiler about the function's existence and how it should be called.

Function Definition

The function definition contains the actual code that executes when the function is called. It specifies what the function should do when invoked.

Function Call

To use a UDF, you need to call it within your program. The function call triggers the execution of the code within the function.

Advantages of Using UDFs

User Defined Functions offer several benefits, including code reusability, better organization, and improved readability. They allow programmers to break down complex problems into simpler, manageable parts.

How to Declare and Define a UDF

Creating a UDF involves two main steps: declaring the function prototype and defining the function. This section explains how to do both.

Parameters and Return Values

UDFs can accept parameters and return values, enabling them to work with different inputs and produce varying outputs. We'll explore this aspect in detail.

Scope and Lifetime of Variables

Understanding the scope and lifetime of variables within UDFs is crucial for preventing bugs and optimizing memory usage.

Recursion in User Defined Functions

Recursion is a powerful technique where a function calls itself. We'll investigate how recursion can be applied in UDFs.

Best Practices for Using UDFs

To make the most of UDFs, it's essential to follow some best practices. These guidelines ensure your code remains efficient and maintainable.

Error Handling with UDFs

Learn how to implement error handling mechanisms within your UDFs to make your programs more robust and user-friendly.

UDFs in Real-world Applications

Explore real-world scenarios where User Defined Functions play a pivotal role in solving complex problems efficiently.

Case Study: Creating a Calculator Program

We'll walk through a practical example of building a calculator program using UDFs, demonstrating their practical application.

Performance Considerations

Discover how UDFs impact the performance of your C programs and strategies for optimizing their execution.

Conclusion

In conclusion, User Defined Functions in C Programming are indispensable tools that enhance code modularity, readability, and efficiency. By creating functions tailored to specific needs, programmers can simplify complex tasks and build more maintainable software.

my term paper written in 2018 (how ND games were made and why they will never be made that way again)

hello friends, I am going to be sharing portions of a paper i wrote way back in 2018 for a college class. in it, i was researching exactly how the ND games were made, and why they would not be made that way anymore.

if you have any interest in the behind the scenes of how her interactive made their games and my theories as to why our evil overlord penny milliken made such drastic changes to the process, read on!

warning that i am splicing portions of this paper together, so you don't have to read my ramblings about the history of nancy and basic gameplay mechanics:

Use of C++, DirectX, and Bink Video

Upon completion of each game, the player can view the game’s credits. HeR states that each game was developed using C++ and DirectX, as well as Bink Video later on.

C++

          C++ is a general-purpose programming language. This means that many things can be done with it, gaming programming included. It is a compiled language, which Jack Copeland explains as the “process of converting a table of instructions into a standard description or a description number” (Copeland 12). This means that written code is broken down into a set of numbers that the computer can then understand. C++ first appeared in 1985 and was first standardized in 1998. This allowed programmers to use the language more widely. It is no coincidence that 1998 is also the year that the first Nancy Drew game was released.

C++ Libraries

          When there is a monetary investment to make a computer game, there are more people using and working on whatever programming language they are using. Because there was such an interest in making games in the late 1990’s and early 2000’s, there was essentially a “boom” in how much C++ and other languages were being used. With that many people using the language, they collectively added on to the language to make it simpler to use. This process ends up creating what is called “libraries.” For example:

          If a programmer wants to make a function to add one, they must write out the code that does that (let’s say approximately three lines of code). To make this process faster, the programmer can define a symbol, such as + to mean add. Now, when the programmer types “+”, the language knows that equals the three lines of code previously mentioned, as opposed to typing out those three lines of code each time the programmer wants to add. This can be done for all sorts of symbols and phrases, and when they are all put together, they are called a “package” or “library.”

          Libraries can be shared with other programmers, which allows everyone to do much more with the language much faster. The more libraries there are, the more that can be done with the language.

          Because of the interest in the gaming industry in the early 2000’s, more people were being paid to use programming languages. This caused a fast increase in the ability of programming. This helps to explain how HeR was able to go from jerky, bobble-headed graphics in 1999 to much more fluid and realistic movements in 2003.

Microsoft DirectX

          DirectX is a collection of application programming interfaces (APIs) for tasks related to multimedia, especially video game programming, on Microsoft platforms. Among many others, these APIs include Direct3D (allows the user to draw 3D graphics and render 3D animation), DirectDraw (accelerates the rendering of graphics), and DirectMusic (allows interactive control over music and sound effects). This software is crucial for the development of many games, as it includes many services that would otherwise require multiple programs to put together (which would not only take more time but also more money, which is important to consider in a small company like HeR).

Bink Video

          According to the credits which I have painstakingly looked through for each game, HeR started using Bink Video in game 7, Ghost Dogs of Moon Lake (2002). Bink is a file format (.bik) developed by RAD Game Tools. This file format has to do with how much data is sent in a package to the Graphical User Interface (GUI). (The GUI essentially means that the computer user interacts with representational graphics rather than plain text. For example, we understand that a plain drawing of a person’s head and shoulders means “user.”) Bink Video structures the data sent in a package so that when it reaches the Central Processing Unit (CPU), it is processed more efficiently. This allows for more data to be transferred per second, making graphics and video look more seamless and natural. Bink Video also allows for more video sequences to be possible in a game.

Use of TransGaming Inc.

          Sea of Darkness is the only title that credits a company called TransGaming Inc, though I’m pretty sure they’ve been using it for every Mac release, starting in 2010. TransGaming created a technology called Cider that allowed video game developers to run games designed for Windows on Mac OS X (https://en.wikipedia.org/wiki/Findev). As one can imagine, this was an incredibly helpful piece of software that allowed for HeR to start releasing games on Mac platforms. This was a smart way for them to increase their market. 

          In 2015, a portion of TransGaming was acquired by NVIDIA, and in 2016, TransGaming changed its business focus from technology to real estate financing. Though it is somewhat difficult to determine which of its formal products are still available, it can be assumed that they will not be developing anything else technology-based from 2016 on.

          Though it is entirely possible that there is other software available for converting Microsoft based games to Mac platforms, the loss of TransGaming still has large consequences. For a relatively small company like Her Interactive, hiring an entire team to convert the game for Mac systems was a big deal (I know they did this because it is in the credits of SEA which you can see at the end of this video: https://www.youtube.com/watch?v=Q0gAzD7Q09Y). Without this service, HeR loses a large portion of their customers.

Switch to Unity

          Unity is a game engine that is designed to work across 27 platforms, including Windows, Mac, iOS, Playstation, Xbox, Wii, and multiple Virtual Reality systems. The engine itself is written in C++, though the user of the software writes code in C#, JavaScript (also called UnityScript), or less commonly Boo. Its initial release took place in 2005, with a stable release in 2017 and another in March of 2018. Some of the most popular games released using Unity include Pokemon Go for iOS in 2016 and Cuphead in 2017.

          HeR’s decision to switch to Unity makes sense on one hand but is incredibly frustrating on the other. Let’s start with how it makes sense. The software HeR was using from TransGaming Inc. will (from what I can tell) never be updated again, meaning it will become virtually useless soon, if it hasn’t already. That means that HeR needed to find another software that would allow them to convert their games onto a Mac platform so that they would not lose a large portion of their customers. This was probably seen as an opportunity to switch to something completely new that would allow them to reach even more platforms. One of the points HeR keeps harping on and on about in their updates to fans is the tablet market, as well as increasing popularity in VR. If HeR wants to survive in the modern game market, they need to branch outside of PC gaming. Unity will allow them to do that. The switch makes sense.

          However, one also has to consider all of the progress made in their previous game engine. Everything discussed up to this point has taken 17 years to achieve. And, because their engine was designed by their developers specifically for their games, it is likely that after the switch, their engine will never be used again. Additionally, none of the progress HeR made previously applies to Unity, and can only be used as a reference. Plus, it’s not just the improvements made in the game engine that are being erased. It is also the staff at HeR who worked there for so long, who were so integral in building their own engine and getting the game quality to where it is in Sea of Darkness, that are being pushed aside for a new gaming engine. New engine, new staff that knows how to use it.

          The only thing HeR won’t lose is Bink Video, if that means anything to anyone. Bink2 works with Unity. According to the Bink Video website, Bink supplies “pre-written plugins for both Unreal 4 and Unity” (Rad Game Tools). However, I can’t actually be sure that HeR will still use Bink in their next game since I don’t work there. It would make sense if they continued to use it, but who knows.

Conclusions and frustrations

          To me, Her Interactive is the little company that could. When they set out to make the first Nancy Drew game, there was no engine to support it. Instead of changing their tactics, they said to heck with it and built their own engine. As years went on, they refined their engine using C++ and DirectX and implemented Bink Video. In 2010 they began using software from TransGaming Inc. that allowed them to convert their games to Mac format, allowing them to increase their market. However, with TransGaming Inc.’s falling apart starting in 2015, HeR was forced to rethink its strategy. Ultimately they chose to switch their engine out for Unity, essentially throwing out 17 years worth of work and laying off many of their employees. Now three years in the making, HeR is still largely secretive about the status of their newest game. The combination of these factors has added up to a fanbase that has become distrustful, frustrated, and altogether largely disappointed in what was once that little company that could.

Pressenting myself (and this silly little blog)

Well, I've been using this account for +2 years (according to Tumblr's notification system), so I think it's a good time to introduce myself...

"I'm the weirdest person alive"... You'll see why:

I'm autistic. That alone makes me really weird. "Now everyone is autistic these days" "You just want to feel special"... I have the diagnosis since 2012, way before autism was a "trend" (I don't have a better term)... So FCK YOU!

I'm a Linux enthusiast. However, I won't impose Linux on ya, even less any particular software (seestemdee bad, ooboontoo bad, kaydee-e bad >:c /j)

I'm a math nerd. If you know math blogs, let me know (better if they are college-level math, and even better if they're high-level math [topology, real analysis, functional analysis or more advanced])

I study computer science. Anything about computers and programming makes my day :D (I'm also into theoretical Comp. Sci., things like automata theory, lambda calculi, category theory, etc.)

Yes, as an Arch user btw, I'm queer af. My labels are: quadrigender (four genders at the same time), gender fluid (5%), pangender (5%), trans woman, transfemme (85%), xenogender (5%, I know how to define it but don't know if it currenty exists [if not, I'm gonna coin it]), fictionkind (I have the "soul" of a fictional race, if you will, more on it later), bisexual, panromantic, polyamourous

My interests are kinda limited. I love Undertale, Minecraft, Terraria, TBoI, Spiderman I/ATSV, D&D, Pathfinder and WoD. On the later, I LOVE Mage the Ascension, and my fictionkind race is a Orphan Mage.

I'm kinda into philosophy. I suspect I might have AHDH (not autodiagnosing tho), so I find kinda hard to start reading ACTUAL philosophers (specially people like Hegel and Kant, who ABUSE of weird jargon), but I usually read Wikipedia articles about the topic (which, despite misconceptions, it's actually a reliable source)

I'm an anarchist. I read a few anarchist and marxist authors back at the day, and I'm starting to do actual praxis. I consider myself an "anarchist without labels", as I see all anarchist branches having their valid point but also falling into fallacies and biases (DISCLAIMER: I don't see any right-winger "anarchism" as actual anarchism. If you're "anarcho"-capitalist/monarquist/fascist [yes, those exist, apparently], GO FCK YOURSELF!!!

And despite all the previous items (except 1st and 5th), I'm highly spiritual. I believe in anything mystical, religious, esoteric or spiritual there might be out there... And I mean EVERYTHING... I have my way to make sense out of it.

Welp, I think that's all...

Substance Abuse Continued use of research Continued use of research in professional life: Stable housing for substance abusers Substance abuse is strongly correlated with a wide array of risky behaviors, including a failure to live in some form of stable housing, as well as high-risk sexual behaviors. This is significant, because stable housing situations in the form of rehabilitation centers or 'halfway' homes are often used as bases of treatment for addicts. However, a review of the existing literature indicates that simply providing housing for addicts should not be regarded as a panacea or as an automatic form of treatment for addiction. In fact, the results are mixed regarding a correlation between substance abuse and the ability to obtain stable housing. For the purposes of this review, a definition of 'stable housing' will be defined as "not having lived on the street" versus "living in a shelter or single room occupancy hotel (SRO)" at any time in the past 6 months (Des Jarlais 2007). Literature review According to Palepu (et al. 2010), "unstable housing and homelessness is prevalent among injection drug users (IDU)" and finding a stable housing situation is often a critical component of drug treatment for substance abusers. However, in a study of 992 intravenous drug uses, "exposure to addiction treatment" and "the attainment of stable housing among participants who were homeless or living in single room occupancy (SRO) hotels…was negatively associated with attaining stable housing and may have represented a marker of instability among this sample of IDU " (Palepu 2010). This caused the authors of the study to surmise that the most effective housing placement was actually occurring outside of addiction treatment. Thus, surprisingly, addiction treatment was associated with persons less likely to have found stable housing, despite the clear intent of most treatment programs to introduce a more stable life situation for participants. Drawing upon these findings, it seems probable that addicts only seek treatment after addiction has had an extremely negative impact upon their life situation, and has made them less likely to be employable and able to fit into society. Even after addiction treatment, these 'hardened' addicts still struggled with finding housing, more so than addicts with 'less' treatment. This clearly reflects the tendency towards recidivism within most substance abuse programs. The results point to a larger goal for addiction treatment as a whole: rather than simply focusing upon attempting to find stable housing for hardened addicts, also focusing upon treating addicts before their situation has had a negative impact upon their housing situation and their ability to hold a job is the wider policy is wise. The suggestion that addiction treatment is negatively associated with the ability to find stable housing does not mean that improving addicts' housing situation is still not a laudable goal, though. According to Des Jarlais (2007) in a study of substance abusers in 15 syringe exchange programs who engaged in injection risk behavior, there was consistently "more frequent injection risk behavior among unstably housed exchange participants" (Des Jarlais 2007). A lack of appropriate social controls, as imposed by a lack of a stable housing situation, can have an extremely negative effect upon substance abusers. The need to find stable housing not only normalizes the addict's life and hopefully increases exposure to treatment but can also protect the addict against the risks associated with dangerous needle use, such as Hepatitis C and AIDS. From a public health perspective, stable housing can thus perform an important function for society as well as heal the individual addict. In the study, Des Jarlais (2007) also noted that of participants in substance abuse programs, there was a "lack of significant variation in the odds ratios for increased injection risk" suggesting that "none of the programs were 'better' or 'worse' at reducing injection risk behavior among unstably housed participants" (De Jarlais 2007). Once again, there was an extremely high rate of recidivism for programs for addicts and a notable lack of efficacy, suggesting a need for "dramatically new interventions to reduce injecting risk behavior" given the failure of current programs to result in permanent life changes (Des Jarlais 2007). However, another, smaller study 336 adult women supported the usefulness of providing stable housing for female drug users identified at high risk for engaging in HIV risk behaviors: stable housing was associated with lower-risk behavior, regardless of the specific program in which the women were enrolled (Elifson 2007). Conclusion Neither stable housing nor existing addiction treatment programs are 'silver bullet' solutions to the problem of drug abuse. There are some indications that stable housing can reduce risky behavior in addicts. However, making use of treatment programs is often associated with a more unstable lifestyle, indicating that many existing programs are inadequate in addressing the full range of problems suffered by drug users which lead to homelessness and behaviors that put users at risk for HIV. Early intervention, before the behaviors associated with addiction become entrenched is a vital component of treatment, given that even repeated participation in programs show mixed ore relatively moderate positive results for hardened addicts.

Understanding isspace() in C: How It Works and When to Use It

Today, I want to discuss the isspace in c, which is a useful tool when dealing with whitespace characters in strings and input processing. What is isspace()? The isspace() function is part of the C standard library and is defined in the header file. It is used to check whether a given character is a whitespace character. Whitespace characters include: Space (' ') Tab ('\t') Newline ('\n') Carriage return ('\r') Form feed ('\f') Vertical tab ('\v') If the character passed to isspace() belongs to one of these categories, the function returns a nonzero (true) value; otherwise, it returns zero (false). Syntax: c Copy Edit

include

include

int main() {  char ch = ' ';  if (isspace(ch)) {  printf("The character is a whitespace character.\n");  } else {  printf("The character is not a whitespace character.\n");  }  return 0; } Use Cases: Removing Extra Spaces from Input: isspace() is useful when processing user input to trim unnecessary spaces. Tokenizing Strings: When splitting strings based on whitespace, isspace() can help identify separators. Parsing Files: When reading structured data, it ensures proper handling of formatting spaces. Example: Removing Extra Spaces from a String c Copy Edit

include

include

void removeExtraSpaces(const char str) {  int in_space = 0;  while (str) {  if (isspace(str)) {  if (!in_space) {  putchar(' ');  in_space = 1;  }  } else {  putchar(str);  in_space = 0;  }  str++;  } } int main() {  char text[] = " Hello world! This is C. ";  removeExtraSpaces(text);  return 0; } Output: csharp Copy Edit Hello world! This is C. Things to Keep in Mind isspace() only works with characters; passing a string will cause compilation errors. It relies on the locale settings, which may affect its behavior in non-standard environments. Always include to avoid implicit declaration warnings. Conclusion The isspace() function is a small but powerful tool in C programming. Whether you're dealing with user input, text formatting, or parsing files, it can help efficiently manage whitespace.
