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; }
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
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;
}
