Consider the following object:

class Z {

public:

int size;

int *n;

Z(int a=10) {n = new int[a]; size = a;}

};

(a)[5 points] What happens when this class is copied with the default copy constructor?

(b)[10 points] Implement a copy constructor for Z that makes a deep copy of the object.

(c)[5 points] Is there another member function we should also implement with the copy constructor to ensure the object is used properly? If so, implement it as well.
