This document contains instructions for a C++ programming exam with two questions worth 40 marks each. Question 1 asks students to design and implement a class to represent real numbers with integer mantissa and exponent. The class should include a constructor, overloaded multiplication operator, and a printing function. Question 2 asks students to design a class hierarchy for telephone customers with base and derived classes for different types of customers. Students should implement the classes with appropriate data members and functions, demonstrate polymorphism using a print function, and include a constructor in each class.

- 1. No. of Printed Pages : 2 SET-2 BACHELOR IN COMPUTER APPLICATIONS (BCA) Term-End Practical Examination 00806 June, 2011 CS-72P : C++ AND OBJECT ORIENTED PROGRAMMING Time allowed : 2 hours Maximum Marks : 100 (Weightage : 15%) General Instructions : (i) There are two compulsory questions in this paper of 40 marks each. Rest 20 marks are for viva-voce. (ii) You must write the appropriate main( ) function and test your programs. (iii) Write/print the programs, input and results on your answer-script. (iv) Make and state suitable assumptions, if any. 1. Design and implement a class using C + + that stores a real number as integer mantissa 40 and exponent. For example, the number — 2.345 x 105 will be represented as : — 2345 x 102 Mantissa (Integer) — 2345 Exponent 2 The class should have a constructor that takes integer mantissa and exponent value to create the object of the real number class. The class should also include an overloaded x (multiply) operator; and a member function that prints the stored number as : "Mantissa : — 2345 Exponent : 2 " 2. Consider the following hierarchy along with the suggested data members of the 40 classes : Data members • Customer ID Telephone Customers • Customer - Name • Credit - Limit • Year of becoming customer Cellphone Customers Land Line Customer • Mobile ID • Address • Internet use limit CS-72P/S2 1 P.T.O.
- 2. Design and implement the classes in the hierarchy using C + + . You may add more data members in the classes. You should include at least one constructor in each class. Also include a member function print_customer_info ( ) in each class that prints all the information of the object of that class. You should demonstrate polymorphism using this print_custormer_info ( ) function and appropriate main ( ) function. CS-72P/ S2 2 4,000
