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.

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...
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 ...
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...
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, ...
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 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: ...
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...
Since I don't think the C standard says anything explicitly about cases like this, it is probably undefined behavior, under the "not mentioned in the standard" variety. If something isn't mentioned...
The ambition of this site was always to give more room for subjective and big picture questions compared with Someplace Else. However, I believe programming language design falls under the topic of...
As someone who spent a lot of time trying to get this to work on Stack Overflow, I would advise against it. Some background story of my merry adventures with book lists: The story starts around...
C++ doesn't have error codes/exit codes other than return 0; / EXIT_SUCCESS / EXIT_FAILURE. The code you are getting is from the OS when your program crashes from a run-time error. -1073740940 is ...
In addition to all the examples I gave in my answer to the linked post, all scenarios where p is a pointer to incomplete type fails. Not just the void* scenario, but also when p is a pointer to an ...
Performance-wise, I'd benchmark this vs if(memchr(src,'\0',n)==src+n) memcpy(dst, src, n); because it isn't obvious at least to me if that's faster or slower than your custom function. Regarding...
The term escape sequence apparently dates back to the telegraph and pre-computer technology, according to wikipedia: https://en.wikipedia.org/wiki/Escape_sequence. So I doubt there's an universally...
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...
Warnings most often mean "here is a bug which will likely cause your program to crash or misbehave". They do not mean "here's something that you can optionally fix when you can spare the time". See...
https://software.codidact.com/posts/277536/278390?sort=score At the point when I'm posting, the answer by Lundin has +14 score and the answer by dmckee has +11 score. Neither has any down votes. ...
I went ahead and made a proposal on Power User that a separate category for office suites should be made. I suggest that we wait and see where that proposal lands. If a category for these question...
There are many things we label as bad when programming, for various reasons. Repeating code is slightly bad. But writing function like-macros is extremely bad. You should not try to replace someth...
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...
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 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 ...
These are fine, IMO: Here is my specification of what the program should do /--/. I'm stuck at x, (optionally: here is my code), where do I go from here? Is this implementation of x (code follows)...
