"Goes To" operator: --> - Y_Less - 27.12.2018

Goes To

Just a brief tutorial to tell people about the “goes to” operator: -->. The arrow design is to show it goes towards the number, thus it decrements a variable until it reaches zero, and can be used in loops to loop a number of times. Mainly the while loop:

Code:

new i = 10;
while (i --> 0)
{
    printf("%d", i);
}

Will print:

9
8
7
6
5
4
3
2
1
0

Note that 10 is not included, while 0 is. This makes it like normal loops, but backwards.

You can loop over players backwards with:

Code:

for (new i = MAX_PLAYERS; i --> 0; )
{
}

Technically you can go down to any value:

Code:

new j = 10;
while (j --> 5) {}

And yes, if you haven’t figured it out yet, this isn’t actually a new operator. It is two operators (-- and >) with odd spacing. That last example would be more normally written as:

Code:

new j = 10;
while (j-- > 5) {}

I first saw this here: https://stackoverflow.com/questions/...-operator-in-c so though I’d write it here. It is stupid, don't use it...

Interesting

A little stupid but interesting, thank you!

Would it be possible to make with this a some kind of 'countdown' without using the timers or whatever.

What? It's just normal looping behaviour with a stranger syntax.

Weird, though interesting.

Re: "Goes To" operator: --> - iLearner - 28.12.2018

Indeed interesting!

Re: "Goes To" operator: --> - NaS - 28.12.2018

Nice.

Now I'll always omit spaces between an operator and a comparator to make it look like I found a new operator!

We should call them "comperator".

Still nice find, since it's the only combination that looks like what it actually does.

Weird but interesting

Re: "Goes To" operator: --> - Eoussama - 29.12.2018

It took me longer to realize it wasn't some new introduced operator, really interesting and I bet there could be multiple cases of the same trick.

I've been looking for this months ago.
