Q. 2) Attempt any three of the following: (15M)

a) What is a class? How a class can be defined? Discuss various ways of defining member functions of a class.

b) What are objects? How they can be declared? Also, discuss memory allocation for objects in object oriented programming.

d) Write a C++ program to demonstrate conversion from user defined to basic data type.

e) What is this pointer? Write a C++ program to demonstrate use of this pointer.

f) What are virtual functions? What are the rules for writing virtual functions?

 

Q. 4) Attempt any three of the following: (15M)

a) What is inheritance? Discuss different forms of inheritance.

b) Discuss public, private and protected data members and member functions. When to declare which type of data members/member functions.

(i) seekg() and seekp()
(ii) tellg() and tellp()

d) What are class templates? Explain their use. How they can be declared?

e) Define a class named vector. Illustrate the use of vector class template for performing
the scalar product of int type vectors as well as float type vectors.

f) What is a function template? Write a C++ program to demonstrate the use of function
templates?
