How to reset all values in an array

[Hblade]

If you want to reset an array and all of it's values, you first need to know the name of your array you are trying to reset. Lets say we have an array called gameArrays[259]. Place this code in the Global Code area

Code: Select all

void
gameArraysReset()
{
    int i;
    for(i=0;i<258;i++)
    {
        gameArrays[i]=NULL;
    }
}


This should work, now once you execute the command gameArraysReset(); you should be able to reset every value in the array.

Note:
The name of the function is the same as the variable array. gameArraysReset is designed to reset that specific array.

Slightly off topic but can the i<258; part be replaced by i<gameArrays.length?

[schnellboot]

and also it has to be i<=258 because you know the last index is 258 ^^

mhm
Also, if you were to use something like that you'd have to do .length-1 xD Maybe.. or not though

[Troodon]

Yeah, lenght-1 of course. My bad

Wait, so if you have an array like, int myarray[7]; and you want to get it's size, you can just do myarray.length?

[Hblade]

I havent a clue xD

[SuperSonic]

Haha, ok

C doesn't use classes for arrays, so you can't use arrayName.length like you might in other languages. If you really wanted to do that you could create your own derived type for the array, some structure that contained your array and your length count. And it wouldn't be length-1 anyways, since you are handling <. The length of that array is 258 (as the values are 0-257). If it were <= you would need a -1.

Finally, answer to my question. Thanks

[schnellboot]

sky, actually the length of that array is 279 so it is 0-278 ^^

[skydereign]

Ah, I didn't read the actual first post. I just assumed it was 0-277 since people were asking about the length -1. Either way though, the length of an array is its last value, which is the value you use in the for loop (since the standard is < instead of <= in for loop).

Hey Hblade (and others as well) you might want to have a look at this: viewtopic.php?f=5&t=11052#p76692
It's an array resetting function made by me. You just write the name of the array you want to reset and the size of it, or the limit to how far you want it to be limited and it does it all for you!

Very nice!
