lifetime of declaration within a loop

Question

I have a loop as follows

while(1)
{
    int i;
}

Does i get destroyed and recreated on the stack each time the loop occurs?

Answer 1

Theoretically, it gets recreated. In practice, it might be kept alive and reinitalized for optimization reasons.

But from your point of view, it gets recreated, and the compiler handles the optimization (i.e, keep it at it's innermost scope, as long as it's a pod type).
