The code below defines a class Point that represents a point on the coordinate plane. A Segment should connect two points (its end points). When we make a segment, we will give the constructor the addresses of two points - we want the segment to use those points as its endpoints. The segment should link to those points, not make copies of them. (Aggregation)

Finish the Segment class by:

• Adding the member variables p1 and p2 needed to hold the addresses of two Points (OK to do in the public section).
• Making a constructor that accepts two addresses.

Then add code for a moveBy(int deltaX, int deltaY) function to Segment so that we can shift the segment by some amount in x (deltaX) and some amount in y (deltaY). Moving a segment should move its endpoints.

#include #include

using namespace std;

class Point { private: int x = 0; int y = 0; public: Point() { } Point(int xVal, int yVal) { moveBy(xVal, yVal); } string toString() { return to_string(x) + ", " + to_string(y); } void moveBy(int xVal, int yVal) { x += xVal; y += yVal; } };

class Segment { public: string toString() { return p1->toString() + " to " + p2->toString(); }

int main() { Point A(0, 0); Point B(4, 4);

Segment s1(&A, &B);

cout << s1.toString() << endl; s1.moveBy(1, 1); cout << s1.toString() << endl; s1.moveBy(0, -2); cout << s1.toString() << endl; }
