C++ problem

1) Create an array to store 10 Point2D points (the Point2D class from A6). Set the coordinates from 0,0 to 9,9. Move all the points left 5 units and up 10 units. Print their new location. 2) Make a new class Point3D which inherits from the Point2D class. The class has one more data member for the z coordinate. There are two constructors, a default one and one with 3 coordinates. Add the new member functions getZ, setZ and moveAlongZ. Override moveToOrigin and printLocation to do the right thing for all 3 coordinates. Make a few Point3D objects and exercise their functionality.

Point2D class:

#include using namespace std;

class Point2D{

private: int x, y; public: // default constructor Point2D(){ x = 0; y = 0; } // parameterized constructor Point2D(int xp, int yp){ xp = x; yp = y; }

// setters and getters

int getX(){ return x; }

int getY(){ return y; }

void setX(int xp){ x = xp; }

void setY(int yp){ y = yp; }

void moveHorizontally(int xp){ x = x + xp; }

void moveVertically(int yp){ y = y + yp; }

void moveToOrigin(){ x = 0; y = 0; }

void printLocation(){ cout<<"Point at ("<

int main(){

// creating object Point2D p1;

p1.printLocation();

p1.setX(3); p1.printLocation(); p1.setY(-4); p1.printLocation(); p1.moveVertically(2); p1.printLocation(); return 0; }
