Hello, I dont know if you give help with this type of question or not but i thought it would be worth a shot. The program I am creating has functions and stuff. I know how to do all of that. My problem occurs when it comes to calling up the functions. The progrtam has 2 different types of functions to call up or the third option is to quit. I have the functions created and I am just trying to write a fake program that will call up the functions. Instead of calling up the functions right now i am just trying to get the program to output 3 different lines depending on the user input. I give the user the choices of entering the letter 's', 'r', or 'q' as their choice. I have it declared as char choice; When I try to compile the program it says: 's' undeclared (first use this function). It also says the same for q and r. someone told me that I have to assign values to charechter variables and I dont know if that is correct and if so how do i do that? I appreciate any help or response
