A for loop makes a block of statements executed repeatedly for a specified number of times, with its loop index increasing from i_ 0 to a number not greater than i_ last by a specified step ( increment) or by 1 if not specified. The loop iteration normally ends when the loop index reaches i_ last, but it can be stopped by a break statement inside the for loop. The for loop with a positive/negative increment will never be iterated if the last value ( i_ last) of the index is smaller/greater than the starting value ( i_0).
