The document is a past exam paper for an Introduction to C++ course. It contains 5 questions testing various C++ concepts: 1) A program to swap integer variables, the purpose of constructors and destructors, and the difference between virtual and pure virtual functions. 2) A program to find the position of the rightmost occurrence of a substring in a string, and operators that can be overloaded in C++. 3) A program to count lines in a file, and an explanation of abstraction in C++. 4) A program to multiply matrices by overloading the * operator, and differences between cin and scanf statements. 5) Explanations of two C++ exceptions and

CC-16 : INTRODUCTION TO C+ +
Time : 2 hours Maximum Marks : 75
Note : Question number 1 is compulsory. Answer any three
questions from the rest. Use C++ wherever necessary.
1. (a) Write a program to swap the values of two 10
integer variables.
(b) What is the function of a Constructor ? Give 10
an example of Constructor. What is the
function of a Destructor ? Give an example
of Destructor.
(c) What is a Virtual Function ? How does it 10
differ from a Pure Virtual Function ? Also,
give an example of a Pure Virtual Function.
2. (a) Write a program that accepts two strings 10
T1 and T2 as input. The program should
find the starting position of right most
occurrence of T2 in T1 and print the position
to the standard output.
(b) List any five operators of C++ that can be 5
overloaded.
CC-16 1 P.T.O.

2. 3. (a) Write a program that accepts a file as input 10
and prints the number of lines in it.
(b) What is meant by abstraction ? Does C++ 5
support it. Justify your answer.
4. (a) Write a program for the multiplication of 10
two matrices. Overload the operator '*'.
(b) List the differences between cin and scanf 5
statements.
5. (a) Explain any two exceptions supported by 7
C++.
(b) What are templates ? What are their 8
advantages ?
