Point of Sale Program

JarrodBaniqued (8)
This program works just fine when I enter "b" as "entree", but it loops back to the opening statement when I enter "hd". When I enter "ff" after I've typed "b", however, it also closes. Can someone help me here?

The variable, entree, is a char, meaning it can only hold a single character, whereas, your typing two in some instances. Same with side. It also can only hold one character.

you need give char a size because if you don't give him the size the default char takes 1byte

 
 
  char name[10];//now you can write up to 10 char e.g abcdefghij

I already resolved the creation of receipt issues (I don't have a copy of the program with me right now). All I need to do is resolve issues surrounding do-while loops. Can anyone pinpoint the way?
