Answer 2

It uses when u need to go ahead on a list or group of things.. the increment ++ means +1 at every time, when used inside loop it will repeat as long as the loop length .. but if u ask about the diff btwn ++i & i++ that's is ++i incrementing before lunch the statement but i++ increment after
