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.

TL;DR The initialization of the variables a and b in your question are indeterminately sequenced in relation to each other. The initialization order is not guaranteed between them. The initiali...
It is true that MISRA-C has a heavy focus on embedded system, though it has become somewhat more generic over time. The MISRA guidelines have been changed and improved several times over the years ...
When discussing best or safest C programming practices with various C gurus on the Internet, the "MISRA-C guidelines for the use of C language in critical systems" often pops up as a source. This ...
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.
We can't go and shamelessly promote Codidact in SO comments etc just for the sake of it - that's regarded as spamming and might get you banned, plus it will give Codidact a nasty rep. Similarly, SE...
Not using braces is considered bad practice by widely recognized industry coding standards (MISRA-C:2012 rule, 15.6, CERT C EXP19-C and others). Once upon a time I liked to skip out braces too, bu...
Consider using look-up tables to increase execution speed (at the cost of some 200 bytes .rodata use). For example this: static const char specifiers[] = "diouxaefgcspAEFGX"; could be replaced wit...
When posting a lot of code on the site, the "code format window" is much too small: 1 I'm talking about this thing 2 3 4 5 6 7 8 9 10 11 12 13 14 15 The scroll bar appears after...
Luckily, we are in a position where we don't have to re-invent the wheel. We can see what went either wrong or horribly wrong at SO, then avoid making the same mistakes. Some common problems: Maki...
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 ...
Google Sheets isn't a company name, it's a product name. A tag called google-sheets is perfectly fine. Google doesn't market this product as "Sheets", they market it as "Google Sheets". What is not...
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...
There are three different, related concepts that are easy to mix up: null pointers null pointer constants the NULL macro Formal definitions The first two of these terms are formally defined in C1...
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...
I propose that the following is added: On-topic questions asking for code review that follow [the site policies for the code review category]. Where [the site policies for code reviews] is a li...
On-topic questions about SQL programming ... Off-topic questions about database administration I propose that these two are changed to clarify that we allow questions about database design an...
On-topic questions dealing with how to write software documentation I propose that a note about tool use is added: On-topic questions dealing with how to write software documentation or how t...
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-...
There is a new page What type of questions can I ask here? (found under Help -> Guidance.) I'll quote it as whole below, for convenience. Please give feedback on specific items in the list that ...
I agree and I think it should be a separate category, with separate posting rules. There are several examples of how the rules for each category would likely be fundamentally different: Main Q&...
These examples have undefined behavior and unspecified behavior all at once! Operator precedence has nothing to do with the order of execution, see What is the difference between operator precedenc...
I'm experimenting with different operators and have a hard time understanding the outcome of certain expressions. I try to combine the ++ operators with other operators such as assignment in the sa...
The site is called Software Development, not "Applications". Meaning programming. On-topic: Questions about different behavior of web browsers in the context of web application programming. Questi...
We rather need to make a close reason for every kind of off-topic reason. In this specific case, the reason could for example be Purely subjective question rather than the old "primarily opinion-ba...
I believe the term "hook" comes from the Windows API where you can register "hooks" - callback functions - to respond to certain events, optionally replacing the original behavior. Not necessarily ...
