Chapter 14, Problem 21RQE

Consider the following class declaration:

class Thing

{

private:

int x;

int y;

  static int z;

public:

  Thing()

  { x = y = z; }

  static void putThing(int a)

  { z = a: }

};

Assume a program containing the class declaration defines three Thing objects with the following statement:

Thing one, two, three;

How many separate instances    of    the x     member exist?

How many separate instances of     the y     member exist?

How many separate instances     of     the z     member exist?

What value will be stored in the x and y members of each object?

Write a statement that will call the PutThing member function before the objects above are defined.
