The program ends when the number is guessed correctly, otherwise it tries again. It is NOT considered OK to guess at a number more than once, i.e. no repeats. It is counterproductive to try to make this random guessing. Also think about how simple you can make this and still fulfill the wording of the exercises. Just don't run with the first idea you get.
