I'm having a problem with my function "determineWinner". Could someone explain why nothing is being output?

When you compare an int to a character constant you are comparing the character's decimal value to the int. Remember that '1' (a character constant) has a decimal value of 49 not 1.
Because userChoice and computerChoice are ints
In determineWinner you're testing for string values. That's why you're not getting any matches--1 is not equal to '1'.
Thank you for the help.
