insertion operator

I have a class funtion that displays output.
display()
{
  cout<<num<<"/"<<dem<<endl;
}
now I have to overload << in this function


num and dem are private data members.
This function is in a class fraction.
how do I set this up.
before I would call this function like:
fraction f1(2,4);  //sets num=2 dem=4
f1.display;      //this would display 2/4

Please point me in the right direction.

#include <iostream.h>
#include <stdlib.h>

class fraction
{
 // Your stuff here

 friend ostream &operator<<( ostream &stream, const fraction &frac);

};

ostream &operator<<( ostream &stream, const fraction &frac)
{
 stream << frac.num << '/' << frac.dem << endl;
 return stream;
}

void main(void)
{
 fraction f1(2,4);

 cout << f1;
}

OUTPUT: 2/4
