Monica Sabharwal

This document outlines the structure and questions for an exam on Object Oriented Programming using C++. It is divided into two sections: Section A contains 10 multiple choice questions covering topics like detecting end of file, if-else constructs, inline functions, stream classes, manipulators, and static variables. Section B contains 4 longer answer questions asking about object oriented characteristics, user defined data types, constructors, inheritance, passing arguments by reference vs address, abstract base classes, and static vs runtime binding. Students must answer all of Section A and 4 of the 5 questions in Section B.

BCA (SEM. 3rd), MAY -2009 OBJECT ORIENTED PROGRAMMING USING C++ SUBJECT CODE: BC- 304(N2) TIME-03 Hours Maximum Marks: 60 Instruction to candidates: 1) Section A is Compulsory. 2) Attempt any four questions from Section B. SECTION-A (10 X 2=20) Q1) a) How the end of file can be detected? b) Write about if-else construct. c) What are inline functions? d) Define the use of structure in file operations. e) Name two objects of stream class associated with the standard device for error messages. f) Describe the kind of class relationship. Give example. g) What are manipulators? h) Write about sequential input output operations. i) How is a static variable different from a static function? j) What are the advantages/disadvantages of using friend function? SECTION-B (4X10=40) Q2) Explain the essential characteristics that an object oriented program should support? Q3) Explain the user defined data types. How are they used to declare built in data types?
Q4) What are constructors? How to declare a constructor? List the rules while writing a constructor function. Explain with the help of an example. Q5) Define inheritance. What is the inheritance mechanism in C++? What should be the structure of a class when it has to be base for other classes? Q6) (a) Explain the difference between passing arguments by reference and by addresses to functions. (b) What is meant by abstract base class? Explain. Q7) What is the difference between Static binding And Run time bindings? Explain with a suitable C++ code. ***
