What's up, NationStates!

This is a thread for discussion of programming in general. If you want to share your interesting projects in your favourite language, share some neat programming tricks, or sometimes delve into the never-ending war between Emacs and Vim, this is the place for you.

Has nothing to do with ChatGPT, though it may overlap.

I've just started learning [insert language here], what should I do?
The "Reference" section on the right has some cool resources for you. If you're a newbie, I recommend you visit the tutorial site for your language.
It's [insert language here] being updated? How do I keep up with the new versions?
Yes, it's being updated. With each new revision of the language, there would be quite a lot of changes to the language. New features may be added, some features may be deprecated or have its definition/behaviour changed, others may be removed for good. Keeping up with the newest changes will help you code better.
Always check the Wikipedia articles, and the articles on [insert language here]'s official website on newest revisions.
What's C++ used for?
For making tools and programs that are fast enough for people whose works require speed, agility, flexibility and a brain. Speed creates performance, performance creates efficiency; the more efficient the tools, the easier the labour.
A few of the softwares you have on your PC might be written in C++. And that's just for Windows PCs; Linux PCs often have a hundred times more.
Users in NationStates have written a few "scorinators" in C++, for use in sports roleplays.
Can I talk about Python, or Rust, or Java?
Yes. This is the "general thread", after all.
Can I go off-topic?
NO.
This is not TET.
If you want to show your Mandelbrot fractal renderer in C++, then you can.
But if you want to tell everybody that "Chainsaw Man sucks, Makima sucks," do it somewhere else.

That last line isn't going to print - cout only writes to stdout after a newline.

Also if you want you can put "using std::cout;" at the top so you don't have to write "std::" every time.

Cool thread, but unfortunately, I never learned C++.

I will look into installing the compiler + tutorials and check it out.

Learnt any language before?

Thank you for pointing that out.
Remember, I have little experience with C++ though.

Yeah, I know some .php but that is a server side language and its more for web applications. Well, more exclusively for web applications.

Why don't you try out the [code] tag? That'd make things much easier...

Probably because NSGers are not used to using the code tag here. I cannot remember the last time [code] was used in NSG.

I'm not sure if nsg is the best place for this. But it's hard to figure out where it should go instead


We might lock, move or merge this thread


That said, for development, some of the people who build applications on top of the NationStates API hang out in https://discord.gg/SgwWMTN

Hi. Been doing C++ professionally for over 15 years.

I've just started learning C++, what should I do?
The "Reference" section on the right has some cool resources for you. If you're a newbie, I recommend you visit the C++ tutorial site.
(NOTE: I'm a newbie too!)

The tutorial is not the worst I've seen, but has the typical tutorial issue in which there's too much focus on syntax and not enough on best practices, which a language like C++ desperately needs. Don't bother with raw arrays, use std::array instead.

What's C++ used for?
For making tools and programs that are fast enough for people whose works require speed, agility, flexibility and a brain. Speed creates performance, performance creates efficiency; the more efficient the tools, the easier the labour.

C++ being fast is a myth, because in 99% of cases, the relevant slowdown isn't the actual CPU cycle crunching, but rather algorithmic problems. Sloppy C++ will be slower than a comparable program in a compiled but managed language like Java, C#, or Go - and it's very, very, very hard not to write sloppy C++.

A few of the softwares you have on your PC might be written in C++. And that's just for Windows PCs; Linux PCs often have a hundred times more.

Both Linux and Windows platforms have tons of C++. Linux certainly doesn't have "hundred times more", and probably doesn't have more than Windows because most of the standard userspace tools in Windows are written in C++ whereas in Linux you're more likely to find C or a scripting language instead.

---

In 99% of cases, whatever you're doing with C++, is better done with another language. And I say this as somebody that has written hundreds of thousands of lines of C++. Between Rust, Go, Typescript, and C#, you can find an appropriate language and environment for nearly all use-cases you're likely to encounter.

Isn't NSG the place where anything (within reason and the site rules) of the real world can be discussed?

I know this is not a coding site but IMHO, it doesn't make sense why it would be unacceptable on this forum, unless another forum is made for things like this.

I am very sorry. As I said earlier, I am a newbie and I could not find a better manual at the time I wrote the introduction.

Of course. I bet there are C++ coders on varying levels on this site. They certainly can share their creations or answer questions about the benefits of C++'s new features in latest revisions here.

I do feel that this is perhaps a little to narrow. As far as I know we don't have an active Programming Discussion Thread, and I doubt that C/C++ alone will generate enough discussion to keep a thread active over the medium term.

Hi. Been doing C++ professionally for over 15 years.

I did both C and C++ for all of... ah, two years as part of my education. ;p

Based on my limited experience though I agree with the points raised here. Writing C++ projects in my undergraduate years was such a... challenging experience that I don't do it anymore. These days I do my work in Fortran 90 and my course assignments in Python 3.

[Huaren Gongsi state]

Didn't know you're also into C++ as well!

well for me, I haven't learned much (due to school) but I will learn on my sembreak.
I am also looking for an alternative to visual studio (I know) and is thinking about using notepad++ but yeah.

Emacs is way better.

Oh s██t, it's the Editor War all over again.

That last line isn't going to print - cout only writes to stdout after a newline.

Also if you want you can put "using std::cout;" at the top so you don't have to write "std::" every time.

A program ending normally (vs segfaults etc.) will flush its output buffer.
I didn't want to go through the standard, so here's a secondary source: [...], or program termination forces a call to std::cout.flush().

As an extendable basis ("OS") for an IDE, it's awesome. You just need to change the stupid default editor keybinds. Modal editing FTW, and is also a win for your fingers.
Hell, I'd prefer using ed over raw Emacs.
Ed is the standard text editor.

Wow. Emacs is still around. I would use it if the other choice was VI.
