Returning using a void??

[Chinnie15]

Hello!

So, I am completely stuck on my last HW problem. This is the problem it gives to me:

Change the printNumber method :

1. Change the code INSIDE the method to have it RETURN the value.
2. In the main(), create an int value favNum
3. In main(), call the method and have the value returned assigned to the variable favNum
4. In the main(), display favNum

I'm sure I would be fine on the rest if I could only figure out what exactly he's talking about for the first one? How do I return from a void? And I am guessing by 'the value', he means return 23? I don't know why I'm so confused, I did just fine on all the other 5 problems.

This is what I have.

# include <stdio.h>

        /*all prototypes here*/
        void printColor();
        void printGreek();
        void printFood();
        void printSport();
        void printNumber();
        void printSubject();
        void printPet();
        void printCar();
        void printTeam();

        int main()
        {
                /* make all calls from here!!! */
                int favNum;


                return 0;
        }

        /* all methods here */
        void printColor() { printf("Blue\n"); }
        void printGreek() { printf("Pi\n"); }
        void printFood() { printf("Pizza\n"); }
        void printSport() { printf("Hockey\n"); }
        void printNumber() { printf("23\n"); }
        void printSubject() { printf("English\n"); }
        void printPet() { printf("Cat\n"); }
        void printCar() { printf("REG 123 Blazer\n"); }
        void printTeam() { printf("Browns\n"); }

Thank you for any help!

Change the printNumber method :

[LIST=1][*]Change the code INSIDE the method to have it RETURN the value.

I'm sure I would be fine on the rest if I could only figure out what exactly he's talking about for the first one?

Currently, printNumber prints a number. It does not return any value, nor can it, because it is of type void.

So the instruction is a little deceptive: in addition to changing the code inside the function, you will also have to change its type. Ie, the prototype declaration would be:

        int printNumber();

Hopefully you will understand why, and that will be a big clue about how to do the rest.

Nb. There is no other possibility here; a void function cannot return anything, and the instructions you were given confuse this, unfortunately.

Thank you! That's what I thought I had to do, but the way it was worded I thought it would be wrong. I've got it now!
