Hello everyone, I need helping finding out why my program does not work right. I've been trying all last night and this morning to find out what is wrong and tried so many different things but cannot fix this. Please some one help, this is driving me crazy.
the error happens when You push C to continue. After you push C it should prompt the user to select a choice for their sport. But instead of doing this it just skips and goes to the end of the while loop. Please help!!
