Examples

The following example shows how to use the overloaded subtraction operator to subtract a Point3D structure from a Point3D structure.

                  // Subtracts a Point3D from a Point3D using the overloaded - operator.
                  // Returns a Vector3D.

                  Point3D point1 = new Point3D(10, 5, 1);
                  Point3D point2 = new Point3D(15, 40, 60);
                  Vector3D vectorResult = new Vector3D();

                  vectorResult = point1 - point2;
                  // vectorResult is equal to (-5, -35, -59)

                  // Displaying Results
                  syntaxString = " vectorResult = point1 - point2;";
                  resultType = "Vector3D";
