Making program a function

wreidan (13)
Hi guys, the professor wants us to put all the programs we did into functions in 1 program and prompt the user to select which one he wants to run. I have about 8 programs to fit but if you can help me out with just one (as I displayed in my code) I should be able to take care of the rest. The function and the header are in the code as IncTax, I know how to do a function if Im getting the input in the main and using it in the function, but I dont know how to address a function to ask for the input and process the entire thing. Thanks in advance fellas.

       //changed to
    if (selection==1)
        IncTax();


You have got the right idea about how to do it.

good luck
