Question

You must implement the pieces of the below classes on the following pages. You only should implement the functions that are underlined and followed by a "TODO: implement" comment. An example main function is provided to help you test your solution. You may assume the other functions have been implemented correctly, and you may use them. class Point { public: Point(); Point(double, double); double getX() const; double getY() const; void setX(double); void setY(double); void move(double, double); private: double xCoord; double yCoord; public: // output format: (x,y) void display() const; }; class Rectangle { public: Rectangle(); Rectangle(const Point &ll, double w, double h); Rectangle(const Point &ll, const Point &ur); // TODO: implement // Output format - LL:(x,y) W:width H:height void display() const; // Output format - // UL:(x,y) UR:(x,y) // LL:(x,y) LR:(x,y) void displayCorners() const; // TODO: implement // Each returns the specific corner point Point lowerLeft() const; Point upperLeft() const; Point lowerRight() const; // TODO: implement Point upperRight() const; // move the lower left corner of the rectangle void move(double dx, double dy); // TODO: implement private: Point ll; // lower left corner of rectangle double w; // width of rectangle double h; // height of rectangle }; int main() { Rectangle r1 = Rectangle(Point(1,7), Point(5,9)); cout << "r1:\n"; r1.displayCorners(); cout << endl << endl; r1.move(-1.5, 2.5); cout << "r1:\n"; r1.displayCorners(); cout << endl << endl; return 0; } Any implementations belonging in Rectangle.cpp should go in this box:
