Note: Attempt any five question.
All question carry equal marks.
1 (a) What is an object? How can do we use objects in program? Explain about different types of
(b) What are the problems associated with object orientation?
© Discuss about the following:
(i) Method lookup (ii) polymorphism
2. (a) Explain about association between objects by giving proper examples .
(b) Compare object oriented and procedure oriented programming languages .
© We have a function with n arguments . Suggest a way to call this function using less than n
arguments. Give an example.
3. (a) What is this pointer ? Give the most practical use it. Is there any difference between object
points and this pointer ?
(b) Write a program using class pointer to read 20 strings each containing maximum 20 characters .
Write a member function that arranges these in alphabetical order and print the alphabetically
4. (a) Distinguish between the following two statement :
Time T2 (T1);
T1 and T2 are the object of class time.
(b) What is meant by nesting of member functions ? Explain by giving an example.
© What are operator functions ? Define an equal to relational operator function named operator =
= () that can be used to compare two date class having data members day, months and year.
5. (a) What is friend function ? When is it compulsory ? = operator cannot be overloaded by using
friend function . Explain why ?
(b) Why do we need e virtual function ?When to we make a virtual function “Poured “ ?
© Create a class called dimension containing three float data and a constructor to accept values .
Also declare a pure virtual function area () in it create three derived classes rectangle , square
and triangle each inheriting dimension as public . Define corresponding constructors and
redefine virtual function area in each . Write a complete program and also print the version of
virtual function used each time area is printed.
6. (a) How can we achieved run time polymorphism in C++?
(b) Explain about copy constructor.
© Distinguish between the following :
(i) Dynamic binding and Massage passing
(ii) Containership and inheritance
