This is a Tutor Marked Assignment. There are five questions in this assignment. Answer all the questions. You may use illustrations and diagrams to enhance explanations.

Question 1:
(a)What are the five main advantages of object-oriented programming? Describe the meaning of the each advantage by giving a suitable example/ situation for each. (1)

(b) (i) List five different types of objects and five non-objects. Also state why you have put them in the list of objects or non-objects. (1/2)

(ii) Describe the following terms giving one example each: (1/2)

  • Class
  • Inheritance
  • Abstraction
  • Information hiding
  • Encapsulation

Question 2:
(i) What is polymorphism? Explain with the help of suitable example. How can the run time polymorphism be implemented? How is late binding related to polymorphism? Explain with the help of suitable example. (1)

(ii)What are the various object oriented programming languages? Which of them are among the popular languages? Give reasons of their popularity. (1)

Question 3:
What is the need of copy constructors and assignment operator overloading in C++? Describe with the help of suitable examples. (2)

Question 4:
Write a template class “linked queries” in C++. The template class should have functions for adding or deleting an item from the queue after necessary checks. The linked queue is not to be implemented using arrays. (2)

There is one question in this project assignment. Please attach the computer output, where required.

Question 1:
Design and implement a database system using C++ having an inheritance hierarchy for organizing the contents in various subject areas. It should have the following provisions:

  • Initially the contents are to be organized for three subjects: Database Management System, Object Oriented Programming and System Analysis and Design.
  • Each subject has at least 3 sub-areas. These sub areas may overlap.
  • At the lowest level, actual information about a simple item is stored. This simple item may be part of more than one area. For example, one lowest level entity may be Normalisation which is a part of Database Design sub area of DBMS and Database Implementation sub area of System analysis and design subject.
  • There should be a facility for searching of information from this hierarchy.
  • There should be a provision of addition, modification, and deletion of contents at all levels in various areas and also addition/ deletion of subjects.
  • The usage pattern of each item is recorded.
  • There should be a function to print the details of the subject information or area or contents at lower levels.

Note 1: You may add more objects/ functions and use appropriate data structures. You must describe the method you have used for object oriented analysis and design.

Note 2: You may use the following object oriented concepts in implementation:
(a) Virtual Classes and Polymorphism.
(b) Single inheritance and/ or Multiple Inheritance.
