declaration inside class:

       friend bool equal(const Date&, const Date&);


outside function definition:

       bool equal(const Date& left, const Date& right){
       	    if(left.month == right.month &&
	       left.day == right.day &&
	       left.year == right.year)
	            return true;
            else
	            return false;
       }


invocation:

	Date d1.set(3,10,2014);
	Date d2.set(3,10,2015);

	if(equal(d1,d2))
		cout << "Dates match!" << endl;
