Perhaps, but this is not the behavior I see while using Visual C++ 2010 Express.

Maybe you're getting confused output because you're not flushing the output stream (i.e., flush(cout). Another, but less likely, answer might be that the function call is getting optimized away.

Either way you should at least store the values of a and b each time through the loop.
