Question

NOTE: I know I can move the declaration outside the loop.

I want to declare a couple of variables in a for loop:

for ( int x = 0, int y = 0 ; ; )
{
}

,but this doesn’t work since I can’t specify a type after the comma ,. In this case, removing the second int or declaring y outside the loop would fix the problem, but what if I want to declare both variables inside the loop and also have different types?

Can I have something like:

for ( int x = 0, float y = 0 ; ; )
{
}

?

This is impossible; the C++ grammar just won’t admit it. The closest you can get to this is putting an extra scope around the loop:

{
    int x;
    float y;

    for (x=0, y=0;;) {
    }
}
