    adding random numbers and giving a correct or incorrect response back to the user

    /* Mike Shain
    CIS 10 A
    ONLINE
    Project 1

    This program is a Math Tutor program that will ouput different
    random numbers using addition, multiplication, and subtraction.
    It will also tell the user if the answer is correct and the
    print out a report informing the user of how many incorrect and
    correct answers they got.

    If you want someone to at least try and answer your question, better use tags and to write neat code. That way people can at least read it from the beginning till the end
    what does signature stand for?

    void doOneSet('+','-','*');

    huh ? If this is the declaration, use types as parameters, not constants.

    Other than that... what exactly do you need help with ?
    Nice program, but your question is what ?

    She was so Blonde, she spent 20 minutes looking at the orange juice can because it said "Concentrate."

    When in doubt, read the FAQ.
    Then ask a smart question.

    what the program is supposed to do is call the doOneSet() function 3 times and print out a set of problems based off of the operator (+,-,*).

    So basically the first call would print out 5 addition problems and the 6 subtraction problems etc...

    After all that is done as the user does each problem it shows them either correct or incorrect.
