The Point::operator- method subtracts the X and Y data members of two Point objects.
Point operator-( IN const Point & point );
Type: const Point
Reference to a Point object whose X and Y data members are subtracted from the X and Y data members of this Point object.
Type: Type: Point
This method returns a Point object that is the difference of two Point objects.
This method overloads the subtraction operator for Point objects. If A, B, and C are Point objects, the statement C = A - B is equivalent to C = A.operator-(B).
The following example creates two Point objects, then subtracts the second Point object from the first Point object and stores the result in a third Point object.
Point point1(40, 10); Point point2(-20, -30); // Point3 now contains the coordinates (60, 40). Point point3 = point1 - point2;
