I am having issues with a program I wrote for a school project. The program works just fine the first time the user plays the game; but, after the user is prompted to play again, the program skips the part asking for input from the user about the digits he wants to hint at and goes straight into asking the user to input the sum of the remaining digits. Why?

If you have any advice on how to fix this it would be greatly apreciated.
