depends what exactly the looping structure should look like
pseudocode it at the point of entry, where a condition must be checked
better if you can just sketch it up

In C I once had a while loop like this
while(condition) num += 1;

And gcc being a piece of garbage compiled it as if it was
while(condition) num;

Clang is the superior compiler.

Chinese

Fortran

no

Is "pythonic" just what Python babies call functional programming?

The else runs if the while loop exits normally by its precondition. Some languages have it, but its a pretty niche feature.

no

No Python is the anti-functional language.

i don't see why this couldn't just be a while() and then a statement immediately after it, you want it to be executed as soon as the while loop condition is no longer true, right?
that's the same as what you're asking

No, it just means really short code. Personally I think every syntax should strive for that but systems language designers have dysfunctional amygdalas and make ugly languages. See Rust, C, and sepples.

as expected he feels insecure and start name calling because he knows it is true and the language is forever doomed to live under the shadow of c while rust is superior in all possible ways

well, the romanian fascist party isn't far off

If I have a variable x that's of type __m256i, how do I get gdb to print it as v32_int8?

(gdb) p/x reg[3]
$18 = {0x32a230f432a230f4, 0x32a230f432a230f4, 0x0, 0x0}
(gdb) p/x $ymm3.v4_int64
$19 = {0x32a230f432a230f4, 0x32a230f432a230f4, 0x0, 0x0}
(gdb) p/x $ymm3.v32_int8
$20 = {0xf4, 0x30, 0xa2, 0x32, 0xf4, 0x30, 0xa2, 0x32, 0xf4, 0x30, 0xa2, 0x32, 0xf4, 0x30, 0xa2, 0x32, 0x0 }
(gdb) p/x reg[3].v32_int8
Attempt to extract a component of a value that is not a structure.
(gdb)

Why not just do this instead?

while (1) {
// code
if (breaking_condition) {
// more code
break;
}
}

The systems lang debate is a shitshow. They're all garbage. We need something new, not sepples, a C patch, nor Rust, a sepples patch.

if () {
while () {
...
}
} else {
...
}

The else block runs once only if the loop exited without a break.
You need a flag to do it without the lnaguage support I think.

what if expr side effects?

Else will never run if while ran so that doesn't match.
while () {
if(foo) {
///do stuf
break_flag = true;
break;
}
}
if(!break_flag){}

problem with these is you have to skip ahead of some code before you realize there even exists a breaking condition

maybe swapping is better:

while (1) {
if (breaking_condition) {
// more code
break;
}
// code
}

>The else block runs once only if the loop exited without a break.
break through a flag, check for that flag at the end of the loop

Should gotos be straight up banned from every language or should syslangs have it?

Wasn't that the idea?

C++

People who want "goto" to be banned should be banned

Yes, but if you put the condition check at the end and you break before that, the extra code you put in the condition check won't run.

hackage.haskell.org/package/GotoT-transformers-1.0.0.1/docs/Control-Monad-Trans-Goto.html

gotos are fine
in fact, the guy that needs his while to break can just use a goto instead and pop the return stack so it doesn't return there after it's done

F#

can't you just cast it?

How else would you exit an arbitrary nest of loops without outright returning from the function in which they lie?

Its a cult teaching python.org/dev/peps/pep-0020/

Anyone help me brainstorming here for a bit? I'm kinda self-teaching myself node and webdev through trial and error and I found a problem.

I'm doing http requests to retrieve json data from the Jow Forums api, then I perform calculations on this data and output these results to the console. However, if I understand node right, it does these requests asynchronously, so there is no guarantee that when I perform a calculation on the values, the values will actually exist. As a result, when running my program, sometimes I get an error like this

```
JavaScript TypeError: Cannot read property of undefined
```

which I think basically means, the value didn't exist at the time it was being used. But sometimes I don't get this error either. Which I think is basically just luck.

My question is, would it be better to not do calcuations in the http request, and instead just use these to get json and save it locally. Then read the local json file?

Looking around in github.com/SerenityOS/serenity

this is the most readable way of doing it, provided that expr doesn't have any side effects. It's nice since you can easily tell that the condition for the while and if are the same. With it isn't quite as obvious.
I would do it like so:
if () {
do {
...
} while ();
} else {
...
}

using a do-while removes concerns about evaluating the expression twice on the first iteration, and it's still very easy to read.

I know in C++ it could possibly be
if (x == true) {
while (true) {

}
}
else if (x == false) {

}

Why do people think Rust is a C++ replacement?

Because everything you listed is pointless bloat that nobody needs.
That's what's being replaced.

Pathetic Rust-coper

Rust does have metaprogramming. It also has constexpr, although it's not nearly ready for use.

Why I can't I use #include directly?
Why do I have to use #include and use the compiler arg "-lstdc++fs"?
I thought filesystem was part of the standard. I'm using gcc by the way.

Still working on my UI engine. Got multi-window up and running, but it was way more work than I initially planned. Each window gets its own thread for rendering. Then, there's a master thread that handles stuff that relates to all windows.

I don't know about anyone else, but Rust gave me a fear of concurrency. Nim cured it, but it was a long recovery.

Rust has metaprogramming stuff. Probably the only thing I liked about the lang besides its enums

Update your compiler.
GCC 8 doesn't require experimental/
GCC 9 doesn't require -lstdc++fs

Half of those are unnecessary with hygienic macros. constexpr is sure lacking tho

how do i stop doing this

Will java still compile like that?

Restructure your code to use early returns. Stop using "else" after continue/break/return statements.

there's always more c to learn. if you want something different forth and lisp are pretty great. forth and lisp are easy to implement and can be used to create DSLs to enhance your c programs user interface without libbing shit up like a web developer.

it would have entirely removed the while loop and compiled nothing if that were true. unless of course your condition had side effects, but you wouldn't have been that reckless, right?
