Welcome to Software Development on Codidact!
Will you help us build our independent community of developers helping developers? We're small and trying to grow. We welcome questions about all aspects of software development, from design to code to QA and more. Got questions? Got answers? Got code you'd like someone to review? Please join us.

Yes, it is guaranteed to evaluate to true. All variables with static storage duration are set to zero in case of arithmetic types or set to null in case they are pointers. The relevant part is C17 ...
Should we cast the result of malloc? The cast to the intended type is not necessary in C, since during assignment, the void* returned by malloc can be implicitly converted to any other object poin...
What type of questions can I ask here? has gotten rather cluttered since we have added/removed a lot of things along the way. In particular, I think it is hard to get an idea of what's on-topic by ...
I think it should be on-topic with the following distinction: On-topic Technical questions regarding to UI, including mark-up language syntax, how to set properties in RAD tools, how to use gra...
As with anything computer science-related that dates back to the 1960s and 70s, things just happened at a whim. Everything was new and highly experimental back then. Nobody knew how to write or des...
Yes there are references and pass-by-reference in C, though the language has no explicit syntax item called "reference" like C++. In a C context, it is irrelevant that C++ happens to have something...
When reading posts at programming sites such as this one, I frequently encounter people saying things like: "There is no pass-by-reference in C, everything is passed by value." People claiming su...
To use the identifier Node without typing struct Node, you must use a typedef: typedef struct Node{ // this here is a stuct tag int data; struct Node* next; // this has to be struct Node...
I once wrote this post here: Why can't we mix increment operators like i++ with other operators? When using Codidact search looking for that post, I tried to type i++ in the search but it didn't l...
This question was of very poor quality and should have been closed. I closed it but someone disagreed, for reasons unknown. I'm not sure if it's an actual algorithm question or just a request for f...
I propose that we add the following: Off-topic Questions about code golf, programming puzzles and challenges. Please use Code Golf instead.
Generally speaking, pointer arithmetic is undefined behavior unless carried out on arrays. This is how the additive operators behave, C17 6.5.6: For the purposes of these operators, a pointer to...
The simple explanation would be that you simply don't have write access to the path, which is one possibility. Another weird phenomenon that may happen is that you are running a very old C...
Generally speaking, comparison callback functions in C are often implemented to return an integer lesser than zero, equal to zero or greater than zero - depending on if the first object is lesser t...
Storage class specifiers static is strictly speaking a storage class specifier, which is an attribute given to a variable or a function stating how it is allocated, how it is accessible and how lo...
What exactly does the static keyword do in C? I have seen it used in several diverse contexts: 1) As a variable outside a function: #include <stdio.h> static int x = 5; int main (void) ...
This scenario is not yet a problem for this site, but we will get there, since it's a huge problem for Stack Overflow: Someone just picks up a well-known programming language for the first time. T...
The reader is assumed to understand how arrays and pointers work in C. You cannot understand pointers before you understand arrays, and you cannot understand strings before you understand pointers ...
Preface: This is a self-answered Q&A meant as a C string handling FAQ. It will ask several question at once which isn't ideal, but they are all closely related and I'd rather not fragment the p...
Generally these questions are fine, though they should come with specific examples, so that they become clearer and can get narrowed-down. I've done a lot of self-answered Q&A here and the hard...
Generally, I would say: On-topic How to install, configure, trouble-shoot and use tools specifically meant for software development. Compilers, debuggers, IDEs and so on. Asking questions rega...
400 lines is not that big, it should be fine to post the complete program below the Code Reviews post category. I'd post it as separate code formatted blocks with one block per file indeed. A revi...
Many languages support the concept of functors or function objects which are classes only containing a method/member function. Most notably C++ STL was designed around this - whenever you declare ...
The concept you are looking for is referred to as opaque type or opaque pointers. This is the proper method to achieve private encapsulation in C and can also be used for inheritance/polymorphism (...
I'm using an object-oriented design for my C project and trying to implement classes with private encapsulation. How do I do this? Some things I've tried that are problematic: Using a struct f...
