}
void operator+(Point &pt3);
void show() {cout << "x
= " << x << ", y = " << y; } };
void Point::operator+(Point
&pt3)
{
x += pt3.x;
y += pt3.y;
}
int main()
{
Point pt1(3,2),pt2(5,4);

vehicle {
int diesel_petrol;
protected:
int load;
protected:
int load;
public:
voidread_data(float,float)
voidwrite_data(); };
class bus: private heavy_vehicle {
charTicket[20];
