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 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...
memcpy(&y.t, &x, sizeof(x)); is a bit fishy since it would have made more sense to copy into &y or &y.s. None of this is necessarily UB however. Regarding strict aliasing, it doesn...
Please no. I had a bad experience of SO's failed and cancelled "Documentation" project. I raised the same concerns on the Electronics site here. I'll quote that post: The worst that can happen is ...
Standard library functions that should never be used: setjmp.h setjmp() Together with longjmp(), these functions are widely recogniced as incredibly dangerous to use: they lead to spaghetti ...
I propose that the following is added as off-topic: Off-topic Questions with artificial requirements and no practical use, including code golf and code obfuscation. This also covers artificial hom...
Please note that migrate in this context means grabbing the exact post as-is from a SE site and importing it here. This is allowed, with attribution given, as per licensing model. Codidact staff c...
No, it's not helpful, it's far too broad and doesn't make sense to use in combination with any other tag either. It can't be used for searching or categorizing questions either.
Someone told me that I shouldn't write "NULL pointer" with capital letters, because a null pointer and NULL are different terms. And that NULL is a "null pointer constant". What's the meaning of th...
EDIT: This discussion thread is mostly obsolete now that a new draft has been posted on the site. Please take further discussion & proposals to this meta post instead: Community feedback: What ...
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...
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...
If we ignore the part of recommendation questions leading to opinion-based answers, the main concern against these kind of questions is that they don't add anything of value to this site. But also ...
On-topic questions about best practices as long as enough detail is provided to answer using external references or expertise consensus I propose that this should be re-phrased: On-topic non-...
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...
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...
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 kind of comments telling you to add checks against null are typically coming from programmers mostly used to deal with higher level programming languages. They think that generally, more explic...
