If a while or for statement uses a loop counter, and increments or decrements it by more than one, it should use a numeric comparison operator (that is, <, <=, >, or >=) to terminate the loop. This prevents the loop from executing indefinitely or until the counter wraps around and reaches the final value. (See guideline rule NUM00-J. Detect or prevent integer overflow.)
