Answer
any FIVE Questions out of EIGHT Questions.
Each
question carries 16 marks.
Q.2 a. Object Oriented Programming
has two important philosophies : data
hiding and data abstraction.
Explain. (8)
b. What is the difference of C++ struct and C++ class? Is there any difference between C++ struct and C struct?
Explain with suitable examples. (4 + 4 = 8)
Q.3 a. The overloaded index operator [] returns by reference. What
implications will be there if it returns by value? Comment and justify. (8)
b. What is the role of an inline function? How does it differ
from macro? Illustrate with examples. (8)
Q.4 a. Explain and illustrate the use of virtual base class through
suitable examples. (8)
b. What is the usage of this pointer? Can a static member
function of class refer to data pointed by ‘this’? (2 + 2 = 4)
c. What is the implication of putting a 'const' after a member
function declaration e.g.
class X {
void f() const;
}; (4)
Q.5 a. Read from standard input an unknown number of strings. Store
them in a list. Determine both the shortest and longest strings. (6) (4)
b. You are given a text file to read. Write a programme to
compute the byte size of the file and store it at the end of the file. In
addition, each time we encounter a newline character, store the current byte
size, including the newline, at the end of the file. (10)

exception handling model is non-resumptive? Explain what happens during stack unwinding (8)
b Define
a class Stack with push and pop operations. Define a double ended queue in
terms of the class stack. (8)
Q.7 a. When should you define a member
function as virtual? Illustrate through suitable example. (8)
b. Is it possible to provide a special behavior in one
particular instance of a template while not for other instances of the
template? Illustrate through suitable example(s). (8)
Q.8 a. In how many ways can type conversion
(user-defined conversions) of class instances be specified? Explain with
examples. (8)

class through proper example. (8)
