Menu Help

unknown3112 (22)
Everything used to work except my menu part, I am not sure what is wrong. I just want the menu to run once because I have to add more functions after this code. The menu should ask the user what day of the week it is and output it.

The return choice; will not only break the loop it also ends the program since it is in main.

Line 17 is only a prototype of the function. Not the function itself.
