Regarding a programme

#1

I was doing an assignment it is compiled correctly but it is not passing any test cases. Can you help me out??
the problem states that if character is + , - , *, /,% then the program should give correct answer. If the character is x or X program should terminate and if character is any other thing it should restart the programhttps://ide.codingblocks.com/s/437465
