循环前设置整数值

Question

I have a loop like so

    int current = -1;

    for (int i=0; i < size; i++) {
        ... some stuff 

        if (i > current || current == -1) {
            current = i;
        }
    }

So basically, I don't have an original value for current before the loop. Is this a good way to ensure current value is set to the first instance of i or could it be written better?

Thanks.

Answer 1

This one works nicely if current will only be used inside the loop:

for (int i = 0, current = i; i < size; i++) {
    // etc..
}

Answer 2

That's the usual way people do it, yes.

There's no need for current == -1 though, since i > current will evaluate to true the first iteration, and current is set to i after that.
