Simple Enumeration

Hello,
I am just trying to get a good grasp on enums. I created this code just to test to see if i knew how to do it. But i got an error having to do with the ">>" operator. Anyways.. this is wat i have, anyhelp would be greatly appreaciated. Thanks.

PHP Code:


		
			
#include <iostream.h>



int main()

{

    enum Day {MON = 1, TUE, WED, THU, FRI, SAT, SUN}dayoff; 

    cout << "What day do you want off?";

    int x;

    cin >> dayoff(x);

    if (dayoff == 1)

        cout << "Mon";

    else 

        cout << "Tue- sun";

    return 0;

}

Try this instead:

Code:

#include <iostream.h>

enum Day {
        MON=1,
        TUE,
        WED,
        THU,
        FRI,
        SAT,
        SUN};

int main() {
        int x;

        cout << "What day do you want off?";
        cin >> x;
        switch(x) {
                case MON:
                        cout << "Monday";
                        break;
                case TUE:
                        cout << "Tuesday";
                        break;
                case WED:
                        cout << "Wednesday";
                        break;
                case THU:
                        cout << "Thursday";
                        break;
                case FRI:
                        cout << "Friday";
                        break;
                case SAT:
                        cout << "Saturday";
                        break;
                case SUN:
                        cout << "Sunday";
                        break;
                default:
                        cout << "I don't understand your answer";
                        break;
        }
        return 0;

The reason why you are getting errors is because when you enum a set of values, that is exactly what they are, values. They aren't types so you can not use them in that fashion. Think of it as the true & false values. You can't say cin >> false; because false is a value.
Make sense?
