i made a simple password program. the password is a 4 digit number, you enter the password digit by digit and each time you enter one number it checks if it matches. if not you go back to the start. right now everytime you enter a number you need to press enter to have it checked, i would like for it to check everytime a number is entered instead of needing to press enter. im sure its something simple but this is my first c++ attempt :]
