thanks!! that solves my first problem. I keep forgetting that the = is actually not a =, but assign a value to an variable

how do I get the program to return to the menu?
Use a do-while loop, and prompt the user if he wants to do another calculation or if he wants to quit.

If you just want it to loop forever just put a while(1) loop around your code.
