                                      Section - A

Q1) When a child class inherits from a base class, will the child class inherits everything of the base class, including all member variables and functions? Also explain the difference between abstraction and data hiding?

Q2) What are the advantages of polymorphism and dynamic binding? With a suitable example explain how to design a class. Give all possible representation in a class (name, attribute, visibility, methods, and responsibilities).

                                      Section-B

Q3) What is the difference between a "assignment operator" and a "copy constructor"? What is the meaning of polymorphism?

Q4) How can C++ achieve dynamic binding yet also static typing? When should destructor be virtual?

                                      Section-C

Q5) What are the differences between overloading and overriding? Are they both concepts of polymorphism? Can I call the constructor of the base class? Can constructors be overloaded? Justify each answer.

Q6) What are various types of files? What are the various modes in which a file can be opened? Explain by giving examples.

                                      Section-D

Q7) Give guidelines for identifying objects in object oriented, I analysis. Compare Object Oriented Analysis and data structure oriented analysis.
