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.

@Monica Cellio Ok. Seems a bit cumbersome to monitor _n_ number of metas instead of one, though? (more) |

Sounds like a network-wide problem and arguably it is a bug. Might want to post this on https://meta.codidact.com/ so that it gets attention from the right people. (more) |

"In short, register and cache storage don't play any part..." Well, they do. Because not all computers have a stack: there's very low end microcontrollers that are stripped down of everything to reduce price, typically used for consumer electronics. On such admittedly rather exotic computers, you onl... (more) |

This was about C, but C++ behaves the very same up to version C++14. In C++17 and later, as well as all versions of Java, the assignment operator has well-defined sequencing, making `i=i++;` etc well-defined. But C++17 and beyond still does not allow completely wild stuff like `i++ + ++i`. (more) |

A: Why can't we mix increment operators like i++ with other operators? 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 precedence and order of evaluation? From that post we can also learn that most of the above examples have unsp... (more) |

| Question | — |
Why can't we mix increment operators like i++ with other operators? 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 same expression. But I get mighty strange results when I use the same variable more than once. One examp... (more) |

@jrh The main issue besides non-existent structure was quality. There was various excited students writing examples that were just plain bad or incorrect. See the various crappy tutorial sites out there as reference for how easy it is to get things wrong. I can relate to the students writing all this... (more) |

A: Are questions about web browsers on topic on Software Applications? 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. - Questions about writing plug-ins for web browsers or accessing an API/library provided by web brows...

But a reasonable speed vs program size compromise could be a 16 bytes large nibble-based one, which doesn't make the program that much slower, but saves 64kb executable size. An answer can list all sensible options if the requirements are listed. (more) |

| Comment | Post #278265 |
@Peter Taylor Of course, but you can list which requirements are the most important. Such as for example 1) execution speed (most important) 2) RAM use (important) 3) executable size (less important). If the question then is how to implement some search algorithm for a 16 bit integer key, the pure s... (more) |

This particular community will need a number of specific close reasons though, such as "the question is looking for debugging help but didn't provide the minimum code necessary to reproduce the problem" etc. (more) |

| Comment | Post #278238 |
I agree with you overall, we should have a list of valid close reasons, as per community consensus. We can't have users closing questions based on personal whims or believes. Ideally the close reasons should be well-defined and maybe we can also give a number of examples of what such an off-topic que... (more) |

A: Give actionable feedback when closing questions 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-based". Because we hope to allow some form of best practice & design questions here and not be as stri... (more) |

The problem is rather that the community has yet to define what's actually on scope here. I gave it a try here: https://software.codidact.com/questions/277235, but it sits at +5/-2 so hardly "community consensus". I think we might need a retake on that, maybe let the community vote on individual deta... (more) |

Also, in the early stages of a new site, self-answered Q&A can be used to get the activity going and demonstrate what kind of questions that are suitable for the site. Or at the very least show that the site is alive, if there are not enough people asking questions. (more) |

| Answer | — |
A: What is the difference between a hook and a code injection? 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 other processes, it could also be hardware events etc. If you wish to respond to events occurring ins... (more) |

Btw keep in mind that this was all decided in 1989-1990. Compilers back then were pretty horrible at optimizing code in general. `register` as a sensible manual optimization still made perfect sense. Other such primitive, manual tricks like `inline` had not even been considered. Modern C compilers in... (more) |

A: Do we want a wiki (or similar) alongside Q&A? 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.

@Derek Elkins That's how the rationale was explained to me by someone who was a member of the ANSI C/C90 committee. ISO in particular is very picky with not giving a particular technology an advantage/disadvantage. (That's also the reason C supports dysfunctional things like one's complement and sign... (more) |

As for compilers, the very point here is that the code has unspecified behavior and may behave differently between any number of compilers, or even when executed several times on the same one. But fair enough I can remove that part. (more) |

@msh210 The C and C++ tags are there because this is a self-answered Q&A post which is meant to be used as a canonical dupe link for C _and_ C++ questions. The languages are identical here. We should not close future C questions with a link to C++ or vice versa. Believe me, I know all about the "C/... (more) |

A: What is the difference between operator precedence and order of evaluation? It is a common mistake is to mix up the concepts of operator precedence and order of evaluation. Beginner classes and books often address the former in detail, but forget to mention the latter at all. Operator precedence specifies the order in which an expression should be parsed. It is similar to... (more) |
