Multivariable issues

Hello, I have a program that randomly shuffles cards. Within the switch/case statements I am trying to display 'T' as "10". But I have tried several different ways to define T and it still will only print T instead of 10. A couple of things I have tried is a printf statement after T. I have tried to define T within the case statement, but nothing seems to work. When I try to compile the program with 10 within the ' ' for case (10), it gives me a multivariable error. Below id my code and I will note the place I would like to change the variable T to 10. Any help would be great! Thanks!

Code:

Well, the variable 'c' is just a single character (or rather, an int being used as one). If you need more than that, use an array...
