Instruction to Candidates:

1) Section - A is Compulsory.

2) Attempt any Nine questions from Section - B.

Section - A

(15 x 2 = 30)

Q1)

a) For a two dimensional array int a [2][2], which element is represented by *(a + 1).

b) Differentiate between macros and functions?

c) When should one use references, and when should I use pointers?

d) Explain Function overloading with simple examples.

e) Can I overload the destructor for my class? Support your answer.

f) What do you mean by new and delete operator?

g) What’s the order that local objects are destructed?

h) What is the significance of access specifiers in a class?

i) Explain the role of file iostream.h in C++.

j) Explain the difference between prefix and postfix incremental operator.

k) Write a declarator for main( ) that will enable command line arguments.

l) True or False: A file pointer always contains the address of the file.

m) Explain the use of this pointer.

n) Write a declarator for a pure virtual function called purevar( ) that returns type void and takes one argument of type int.

Section - B

(9 x 5 = 45)

Q2) When do we make a virtual function “public”? What are the implications of making a function pure virtual function?

with a suitable C++ code.

Q9) Explain with the help of suitable example the difference between function

overloading and function over-riding.
