Chapter 11, Problem 18RQE

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; }

};

int Thing:: z = 0:

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

Thing one, two, three;

A) How many separate instances of the x member exist?

B) How many separate instances of the y member exist?

C) How many separate instances of the z member exist?

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

E) Write a statement that will call the putThing member function before the Thing objects are defined.
