Answer 1

Your program does absolutely nothing so this says nothing about the performance of both languages. The only thing it tells you is if your compiler is able to figure this out and therefore completely skips your program.

To make it do "something" you would have to print every increment to stdout. If you print only the end result a good compiler could optimize your program to a statement that just prints this result and skips the whole "computation".
