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.

The problem with undefined behavior due to array out of bounds happens whenever we use pointer arithmetic, which is only defined to work within the bounds of an array. Where plain variables, "scala...
Code review part: Design (important!) Global variables/external linkage are to be avoided (Why is global evil?). You don't actually have private encapsulation in this code since the inte...
The basics of good vs bad program design All programs are divided in classes. (Or modules/abstract data types/interfaces etc - a rose by any other name.) Each class should only be concerned with i...
When looking at this, we might pretty soon note that storing strings in the same buffer by using null terminators as separator is quite clunky. It blocks us from using handy functions like strtok, ...
Software design in itself has always been on-topic, as per https://software.codidact.com/help/on-topic. As for system design for a given purpose, I think it is fine within reason. Contrary to popu...
Arguments in favour of "struct tag style": Less namespace clutter. C has a peculiar name space system where all identifiers belong to one of: labels, tags, members, ordinary. Struct tag style...
C offers two different styles when it comes to structs (and union/enum too). Either declare them using a struct tag only ("struct tag style"): struct my_type { ... }; struct my_type x; Or ...
General/program design: I would have expected a public header file with the API for the whole thing, rather than having some main() test case calling static functions from the same file. Sure,...
Whenever registering to diverse sites on the net, you are often forced to enter a so called "strong password", which would ideally contain both upper case letters, lower case letters, digits, and s...
Simply put: parenthesis are used whenever we suspect that there may be operator precedence issues. Either because the user passed an expression containing several operands and operators to the...
It's an unfortunate analogy. Apart from being confusing, it does indeed assume some basic electronics knowledge. In electronics a short circuit (or the common jargon "a short") does not necessarily...
When reading about various operators used by programming languages, the term "short circuit behavior" is often used. For example in this C code: int a = 0; a && b++ Someone explained t...
Search engine optimization? I thought this goes without saying, but apparently we aren't doing too well there for some reason. The other day I was having a discussion with someone at SO regarding...
I think this is important to consider because it doesn't only concern questions about bad practices or XY questions, but also if we should allow questions with artificial requirements or questions ...
the answer is incredibly long It really isn't - though it might look that way because of the extensive use of large font headlines. I think it is a good answer - there's no problem in discussi...
Categories should be used when the posting rules for certain types of question differ. For example a debugging question posted below Q&A should have a minimal, relevant example. Whereas a code ...
It has 2 parameters for weird historical reasons that nobody seems to know the rationale for any longer. Like most functions in the C standard library, the function API was not well-designed. Keep ...
Ok so we have fairly lax tagging rules here, as do most Codidact sites. Recently the Electrical Engineering community has started a clean-up of strange and off-topic tags. I wrote this over there: ...
C23 will be a major revision, certainly the biggest one since C99. It contains lots of changes and new features, both big and small. The linked draft in the question contains a complete list of cha...
The C language has gone through many iterations and the latest one not yet released is informally called "C23", supposedly because they hoped to release it in 2023. The latest draft version N3096 i...
I don't think there are any formal names for the various versions you list. First of all, please note that output in a programming context most often refers to printing something on a screen or to...
On the contrary, I think that it is appropriate and recommended practice. That way you (the poster of the question) can pick your own answer as the "official" one, since these post often (ought to...
I would recommend to post it anew here as a self-answered Q&A and update it if needed. You can use the "works for me" reaction to label your own answer the "official" one. As an example of how...
Codidact has already managed somewhat to separate domain knowledge from moderator suitability. So far so good, but reputation is also a measurement of activity. It might make sense that being acti...
See Software recommendations category. Referring to my own answer there, I think these questions should only be on-topic in case the OP manages to narrow down the scope sufficiently. In case the qu...
