I don't get this loop, some help please

both answers for the quiz are similar one is

for(int i = 0; i < 5; i++);

the other

for(int i = 1; i < 5; i++);

why is the first one correct and loops?

In the first example, "i" was initialized with the value of 0 and in the 2nd example, "i" was initialized with the value of 1. So after the first irritation, the value of "i" gets incremented by 1 (hence i++). Since the value of "i" is already 1, "i" will have the value of 2 the 2nd time around. After 4 irritations "i" will be equal to 5 so the loop will stop.

yes but this is the question asking for the answer that loops 5 times, wouldn't they both loop to 5?
