No love for self-answered Q&A I guess. So much for getting this site going... If there is any factual errors in the post, I would very much like to know about them so I can improve it. (more) |

| Question | — |
What is the difference between operator precedence and order of evaluation? When doing something simple such as this int a=1; int b=2; int c=3; printf("%d\n", a + b c); then I was told that operator precedence guarantees that the code is equivalent to `a + (b c)`, since `` has higher precedence than `+`. And so the result is guaranteed to be 7 a... (more) |

Also, since we don't have much in the way of rules for tag wiki , it's important that people realize that tag usage guidelines is the single-most important thing to get right. Explaining what a tag and the technology does is really just fluff that people are better off reading at Wikipedia. Take for ... (more) |

@EJP Regarding static variables, I'm not sure why there's some recurring myth about them not getting optimized... just check https://godbolt.org/z/ezoj7q. Not only did the compiler ignore to allocate separate memory for the two static storage variables `a` and `b`, it pre-calculated the result to 3 a... (more) |

@EJP How is "a compiler tries..." untrue? This post isn't meant to be an exhaustive list of every detail that happens during compilation, but a brief overall summary. If a variable has the address taken, then indeed the compiler can't store it in a register. (more) |

@JohnDoea You could propose starting up such a community on Codidact, if you think we can gather enough of a user base to support it. https://meta.codidact.com/categories/10. (more) |

One month later and there's neither a clear consensus nor any constructive discussion. I'm guessing we'll have to stick to a "random programming stuff" site for now. Which is very unappealing to domain experts and power users. Is the aim here to build a much worse and shallow version of SO or somethi... (more) |

So far +5 and none against, so I suppose we should implement this unless someone can make a strong argument against it. I think we need to draft up guidelines for how to post these though. Other questions that fit in with this category might be obfuscation and tasks with artificial requirements ("wri... (more) |

I agree. Writing some self-answered Q&A on topics you know well seems to be a good way to get a site up and running. Shows that there is good content and active users, whereas imported posts don't really say anything about the state of the site at all. (more) |

A: Strategy to migrate meaningful content from Stack Overflow 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 can help out with this. Check out the Writing or Scientific Speculation communities for examples, importe... (more) |

I think https://serverfault.com/ is the closest match, though I haven't used the site so I can't tell if/how welcome the question would be there. Maybe ask on their meta first with a link to this post? (more) |

This isn't a question about software development, but about networking and routing tables etc. So I believe it is off-topic here. (more) |

@BobJarvis Oracle-DBMS, Oracle-database or similar. What we especially wish to avoid is someone using 2 tags "Oracle" and "RDBMS" when referring to a specific product by that company. Then next up we get "Oracle" + "JavaVM" etc. (more) |

As for the cast to void question, it isn't even subjective. There's industry consensus that doing so when a return value isn't used is mandatory, save for a number of old standard library functions that aren't used in that way out of tradition. (more) |

If it is on-topic, then there is no reason to create a tag for this - it becomes a meta tag. It is in my opinion better to spend the effort into drafting help pages for how to ask these kind of questions. (more) |

| Question | — |
Getting rid of "company tags" early on So it appears that we've gotten our first "company tag", Apple. We know from SO that company name tags were always problematic since: - Questions are about products, not companies. - Given that the product tag is present, the company tag doesn't add any relevant information to the question. - Th...

@pnuts I have no idea how it works here really. On SE you had to go through all manner of painful rituals and post reviews. But since this site is brand new, we should be able to be more flexible. (more) |

@Monica Cellio Okay. Then we should probably remove both tags, without or without space. It is too vague to fill a purpose. (more) |

Meaning of the tag software practices? Some new tag "software practices" just popped up, no wiki. What's the purpose of this tag and how is it useful? What exactly in software development is not "software practices"? Seems quite superfluous and very broad. Is it supposed to mark questions that are subjective or asking for best prac... (more) |

@Estela It turns cumbersome to cast everything to `void` when using various common, poorly-designed standard library functions such as `printf`, `strcpy` etc. You do not commonly use the result of those (since it's useless most of the time). (more) |

Maybe I don't understand the problem, but code shouldn't get automatically line-wrapped, since doing so might affect the behavior of it in a lot of languages. (more) |

A: Generate SIGSEGV without undefined behaviour. `SIGSEGV` is defined in the C header `signal.h`. To generate the signal, it should be sufficient to just do `raise(SIGSEGV);`. As far as I know, this is well-defined behavior. (more) |

@obround I'd be surprised if a compiler didn't store small size arrays inside registers, given that the array address is never taken. Easy enough to prove, here is an array stored in registers: https://godbolt.org/z/Yb134Y (more) |

A: How does the community feel about resource requests? 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) fine in terms of parameters y and z? Where parameters could be execution speed, memory use, read... (more) |

A: What gets allocated on the stack and the heap? "Stack vs heap" is a common over-simplification and not really a meaningful one, since those two areas have quite different, specialized uses. And no, those are not the only memory regions used by your program. To understand where variables end up, we must understand how a computer works. Physical... (more) |

| Question | — |
What gets allocated on the stack and the heap? I was told by my professor/book that computer programs use two kinds of memory and that all variables get allocated either on the stack or on the heap. Is this true? How can I tell where a variable gets allocated? Does the compiler handle allocation differently depending on which programming language... (more) |
