variable inside loop

Dear all.

I guess the following is somewhat VC specific question ...
Imagine such a code:

for (int a=0; a<1000; a++)
{
int b;
//<== operations on b
}

I've been wondering if there is any speed related benefit if I had declared variable b outside of the loop. So far I haven't spotted any difference in case of basic types. Otherwise, constructor evoked dozens of times would take up loads of the processing time. Can anyone elaborate on how VC copes with variables of basic types declared inside loops rather than outside?

Cheers,
Peter
