Question

You are to write a class named Rectangle. You must use separate files for the header (Rectangle.h) and implementation (Rectangle.cpp) just like you did for the Distance class lab and Deck/Card program. You have been provided the declaration for a class named Point. Assume this class has been implemented. You are just using this class, NOT implementing it. We have also provided a main function that will use the Point and Rectangle classes along with the output of this main function. You must implement your Rectangle class such that this main function will compile and output exactly as in the example given. The Rectangle display represents the 4 corner Points of the Rectangle. You may declare any private data members and declare and implement any private helper functions for the Rectangle class. You may not change or add anything to the Point class.

Exact output needed:
p: (1,1)
r1:
(0,2)(5,2)
(0,0)(5,0)
r2:
(1,5.1)(4.2,5.1)
(1,1)(4.2,1)
r1:
(2,-1)(7,-1)
(2,-3)(7,-3)

Given:
**************************************Main.cpp**************************************

#include "Point.h"
#include "Rectangle.h"
#include <iostream>
using namespace std;

int main() {
Point p = Point(1.0, 1.0);
Point q;
Rectangle r1 = Rectangle(q, Point(5.0, 2.0));
Rectangle r2 = Rectangle(p, 3.2, 4.1);
cout << "p: "; p.display(); cout << endl;
cout << "r1:" << endl;
cout << r1;
cout << "r2:" << endl;
cout << r2;
cout << endl;
r1.move(2.0, -3.0);
cout << "r1:" << endl;
cout << r1;
cout << endl;
return 0;
}

**************************************Point.h**************************************

#ifndef __POINT_H__

class Point {
private:
double xCoord;
double yCoord;
public:
Point();
Point(double, double);
void display() const; // Display point as (x,y)

double getY() const; // Returns the y coordinate's value
// Moves the Point dx units along the x axis and dy units along the y axis
void move(double dx, double dy);
};
#endif
