Answer the following questions based on the above given program:

1. Which type of Inheritance is shown in the program?

2. Specify the visibility mode of base classes.

3. Give the sequence of Constructor/Destructor Invocation when object of class author is created.

4. Name the base class(/es) and derived class (/es).

Answer 1

1. Multiple inheritance.

2. Private for publisher.

Public for branch

3. branch(); // constructor of branch class

publisher (); // constructor of publisher class

author (); // constructor of author class

∼author (); // destructor of author class

∼publisher (); // destructor of publisher class 

∼branch (); // destructor of branch class

4. Base class(/es): branch and publisher Derived class (/es): author.
