C++ Program

Please help me fix my program to look better

* Needs spacing *A message when the user entered an invalid choice (please add message, ex "Invalid Choice") and the program will just show the options again *A choice when the user wants to exit the program (please add message, ex. "Thank you. Good bye!") and this will stop the program
