Loop headers

The question would be that, which option uses less cpu:

HTML Code:

1. for(new i; i < ArraySize(dynamicArray); i++)



OR



2. 

new lArraySize = ArraySize(dynamicArray)

for(new i; i < lArraySize; i++)

So basically I'm asking if the functions in the header called everytime it's being looped

Re: Loop headers

The second one. You want to aim at having the least number of native calls. Storing the value in a variable will result in ArraySize() being called only once, instead of ArraySize number of times.

Re: Loop headers

And why is that if I create a for loop like this

HTML Code:

for(new i; statement; i++)

the i variable ain't restarted at every loop creating a possible infinite loop?

Then does this whole stuff look something like this?

HTML Code:

for(<done at start>; <checked every loop>; <done every loop>)

Re: Loop headers

You answered your own question. The first part is done when the loop is initiated.

Here's another way to look at it.

PHP Code:


		
			
new i;

for ( i = 15 ; i <= 20 ; i++ )
{ 
     //15 , 16, 17, 18, 19, 20
}

Well, thx, appreciate it!

Re: Loop headers

To add to the first question:
If you used sizeof then for(...; i < sizeof; i++) would be fine since regular array sizes are known at compile time.
