My loop will not exit propery

vinny1 (13)

So I have switch case loop where I must use 10 and 99. 10 is one of my cases and 99 is how you exit the loop. However when the user enters 10 or 99 it reads 1 or 9 and goes to cases 1 or 9 instead.

This is my main function

hi,

make selection an int then remove the single quotes around the cases.

case 99:

A char only hold 1 char.

Cheers
