static in the class

[jacksparrow]

you were right dude ,, thx i fixed the mistakes and at the end there was only one left..i already changed the void main to int main

Error 1 error C2084: function 'int main(void)' already has a body

# include <iostream>
using namespace std;
void sFune();
int main()
{ for (int i=0; i<3; i++)
 sFune();
}

void sFune ()
{
    static int x=2;
    int y=2;
    x++;
    y++;
    cout << " X = "<<x<<endl;
    cout << " Y = "<<y<<endl;
}

    class secretClass
    {
    public : 
        void set ( int a)
        {
            y = a;
        }

        void printY()
        {
            cout <<y<<endl;
        }

        static void printNum ()
