Chapter 15.2, Problem 15.6CP

Suppose a program has the following class declaration:

// Declaration of Checkpoint class.

class Checkpoint

{

private:

int a;

protected:

int b;

int c;

  void setA (int x) { a = x;}

  public:

void setB (int y) { b = y;}

void setC (int z) { c = z;}

};

Answer the following questions regarding the class:

A) Suppose another class, Quiz, is derived from the Checkpoint class. Here is the first line of its declaration:

class Quiz : private Checkpoint

Indicate whether each member of the CheckPoint class is private, protected, public, or inaccessible:

a

b

c

setA

setB

setC

B) Suppose the Quiz class, derived from the CheckPoint class, is declared as

class Quiz : protected Checkpoint

Indicate whether each member of the CheckPoint class is private, protected, public, or inaccessible:

a

b

c

setA

setB

setC

C) Suppose the Quiz class, derived from the Checkpoint class, is declared as

  class Quiz : public Checkpoint

Indicate whether each member of the CheckPoint class is private, protected, public, or inaccessible:

  a

  b

  c

  setA

  setB

  setC

D) Suppose the Quiz class, derived from the CheckPoint class, is declared as
