I need help with my code. My code works fine but it can only run twice. Basically when you run the program once and you finish the game it askes you if another player wants to play. After I run the program twice it automatically ends without asking me if another player wants to play. If someone can please take a look at my code and help me with that I would greatly appreciate that:
