Because i is defined within the loop and the condition of the lopp is, technically, outside the loop. A variable only "exists" within the scope in which it is created, in this case only inside the loop and not outside.

Edit: Do note, however, that a variable created outside the loop is visible within because the loop is contained within the scope in which the variable was created.
