A: What's the difference between Inheritance and Polymorphism? > Does Inteheritance actually meant return and Polymorphism meant to print out values? This doesn't make the slightest sense... Probably you should forget all you've heard - don't "watch tutorials", start over with a good book on the subject written by an actual expert. To answer the questions,... (more) |

How can an off-topic answer even be good or of high quality? That's contradicting. Unless our ambition is to create an "ask about stuff" community where literally everything is on-topic. (more) |

The question is borderline off-topic... but you might want to consider a format which can be used by parsers to present the text in pretty ways. CSV, XML or Doxygen. (more) |

A: Why does this code that uses a pointer-to-pointer-to-int segfault? Bugs: - `int range = 0;` should be `int range;` and then call the function like ` ftultimaterange(&range, min, max);`. That's the whole reason the parameter is pointer-to-pointer, so that you can return a malloc:ed pointer through a parameter. - `while (min `length` (more) |

@#54114 Ignoring the "re-inventing C" argument, then your code is still more verbose than canonical C, which would be `char c = 'A'; say((int)c);`. (Though `'A'` is actually of type `int` to begin with) (more) |

Indeed. This doesn't seem to answer the question, but just tosses out a bunch of generic opinions about random assorted programming languages, without any specific context in mind. (more) |

A: BMPL: The language I'll bring to life First of all, I realize that this is mostly a library you've implemented while learning programming, for the sake of learning, which is great. So I would rather not put a "wet blanket" over your attempts of coding and coming up with libraries, keep on doing that! However, I hope you realize that a... (more) |

How is one expected to use this library? It is custom for library APIs to have one "super header" including all other headers of that library, so I'd expect to find some "bmpl.h" and only include that one. (Note that "super headers" is generally bad practice except for front-end to large libraries.) ... (more) |

A: What compiler options are recommended for beginners learning C? My recommended beginner setup for gcc-like compilers is: `-std=c11 -pedantic-errors -Wall -Wextra -Werror` Here is an explanation of what these options do: - `-std=c11`. gcc & friends are by default set to include non-standard language extensions. These extensions are known as "GNU C" and ex... (more) |

What compiler options are recommended for beginners learning C?

They have spent a lot of time chasing down the bug but failed. Then upon viewing their code, I notice that the code should never have "... (more) |

If there's enough interest I could write another of them self-answered Q&A about how to do OO in C. Private encapsulation, setter/getters, inheritance & polymorphism. There's plenty of examples at SO but I find them lacking. I think I've written a few there myself too but I can't find them. (more) |

A: constructor in C The warnings just say that you can't pass a string literal with type `char[]` to a function taking a `struct Book` parameter. The function should be declared as: void initBooktypes (const char title, const char author, int pages); And in the constructor, `aTitle` needs to be `aTitle->title`... (more) |

@#53922 Depends on the context. During declaration of the variable, you can write `Node* ptr`, `Node *ptr` or `Node * ptr`, it's a matter of style. (the former 2 styles are most common). When _de-referencing_ the pointer to get the items it points at, you always write `*ptr`. (more) |

It's kind of strange that tags have case in the first place. I wonder if they were made that way on purpose. If so, we'd need to come up with guidelines for when & how to use upper case. If not, it just seems like a source for sloppy-looking tags. (more) |

I don't like Discord specifically simply for the reason that it's spyware. Scanning which programs you have installed on your computer and sending that information over the internet, for unclear and highly questionable purposes. It would good to have a chat room though. Is IRC still a thing? :) (more) |

Well I didn't even know there were tool tips before you posted this.

So changing/implementing them might not necessarily h... (more) |

My only concern is that it will seem like the site is just about Office questions and nothing else, it will momentarily "drown out" all other content. But the migration is just a single event, so maybe it should be done sooner rather than later. (more) |

Not sure if I'm following, sorry. Are you proposing that we change the tool tips when we mouse-over the vote buttons? Or are you asking if we should implement a specific page for this community to replace the default https://software.codidact.com/help/voting? Or both? (more) |

Well at this point it doesn't look like my proposal for that category is getting any strong consensus, so it's unlikely to be created any time soon. "Software Category" would just be the general Q&A on Power Users. For now, that's the most suitable place to move all those questions. But it will creat... (more) |

A: Can we migrate office suite related questions to the Power Users community? 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 questions is made, we can go ahead and migrate. (Such a category would also soften the "bump blow" that comes...

Kind of depends on how you define these terms. All of them go back to the earliest days of computing, in some form. Private encapsulation of autonomous "abstract data types" was around very early, long before "modern" OOP emerged in the 1980s somewhere. (more) |

@Monica Cellio No but they will be plenty and risk to drown out all the other content because of it. Just look at Power Users right now, someone dropped 10 or so questions about MS Word there. The same will happen when we migrate all office suite-related questions from here to there. (more) |

Better wait until their scope has settled. If we are not launching an office suite community then it would make lots of sense for Power Users to create a category for it. (more) |

Also, I still think the scope of this site is still too vague for anyone to moderate it.

Generally, we shouldn't use the worst cases of cursing such as the F word because those collide with the "be nice" [code of conduct](https://software.codidact.com/policy/code-of-conduct).

You simply can't discuss proper program design in vague and abstract terms - that's nothing but a source of pointless & badly designed abstraction layers. _What_ is the data that's being passed around and _why_ does it need to be passed around?

A: Etiquette for posting comments Regarding "snark" - it is very hard and subjective to define. Our overall code of conduct says "be nice", but where do you draw the line.
