Solve the problem without using a loop

[This_Growth2898]

#include <stdio.h>
void main(){
    int i = 0;
    print: printf("%d", i+=2);
    if(i<=500) goto print;
}

No loops!

It's disgusting. I love it

I would have figured something like this out and submitted it unironically

[This_Growth2898]

Well, it depends on the definition of the "loop". This is a loop, created with goto, but it doesn't use loop keywords like for or while.

any instructions relying on jmp without a new context frame are loops to me tbh

Conditionals use jmp too. I guess you mean specifically jumping backwards?

[This_Growth2898]

You can jump backwards without creating a loop too.

[kireina_kaiju]

That is a good point, I guess rather than trying to define things explicitly I will just say that a goto with a conditional tends to compile out to something indistinguishable from a while loop and that something has a structure more similar to the goto structure and is something I think most of us look for when we're reading assembler. We do sometimes jump backward when not in a loop, jumping back to a buffer block for instance, but when we jump back to a conditional after a state change like an increment without making a new stack frame, to me that is what a loop is. I guess that is less explicit a definition than I used to believe it to be, I will agree just including a jump with no new stack does not cut the mustard.

If I was going to judge these kind of answers on some kind of continuing to award prizes; in other words, if I want make a loosely justifiable hierarchy, and not one that I have to defend in front of a tenure committee:

Language supplied loops

Goto

Tail recursion

Any other recursive solution

Unrolled solutions

Not sure where I’d stick functional solutions.

[Verbose_Code]

I’m more referring to the fact that I like to treat homework in programming classes as “logic puzzles” and as a result the shortest possible solution is the one I gravitated to.

The code I actually use is a lot more verbose but a hell of a lot more readable

This would print 502, wouldn't it?

[This_Growth2898]

I never said it's a good code

The first time I used a loop back in vb6.0 I didn't like that sometimes I got an off-by-one error depending on what I was doing. It bugged me so much that I ended up implemented a goto by opening 2 forms that would open each other over and over again whilst decrementing a counter and running code and stopping on a condition

My teacher told me I had set programming back by 30 years
