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?

Sergio · Answer 1

3 instances of x member

3 instance of y member

3 instance of z member

Thing : : putThing (2)

Step-by-step explanation:

a) How many separate instances of y member

there are 3 instance of y member

b) How many separate instances of x member

there are 3 instance of x member

c) how many separate instance of the z member

there are 1 instance of z

Statement Call put thing member function we get

Thing : : put thing ()
