Syntax Question for index in a loop

[Halo Fan]

I believe there is something similar to:

if (counter++ && value1 < value2)
{
    //do something
}

and I was wondering if anyone knows what it might be? The purpose is to accurately count the number of key-value comparisons regardless of whether the loop itself executes. I know the idea behind it is that the part regarding the counter always resolves true somehow so that it won't really affect the comparison.
