Total Marks                                                                                                             20




Your assignment must be uploaded before or on 26th May, 2012.

Rules for Making


It should be clear that your assignment will not get any credit if:


  • The assignment is submitted after due date
  • The assignment is copied




This assignment has been designed so that you would be able to implement the concept of Inheritance in OOP. After the completion of this assignment you should have a good grasp on how to implement.


  • Inheritance
  • Aggregation and Composition
  • Using basic constructs of OOP in a program


In previous assignments we have understood all the basics of the Song Library System including the Object Model Diagram and highlighted the Abstraction of classes in terms of attributes and functions prototype. Now it is time to implement the full system in parts, so this assignment is first step towards it.


















Object Model for 4th assignment:



In this assignment you have to code/implement the below said classes in running form these classes are,


  • Music Items
  • Music Category
  • Band
  • Artist
  • Album
  • Track
  • Folk Music
  • Classic Music
  • Film Music
  • POP Music



Now for implementing these three classes practically in c++ you have to define classes according to the requirements (solution of second assignment) given below:


  1. Implement data members and member functions for each class
  2. Implement constructor and destructor for each class
  3. Implement setters and getters functions for each class
  4. Implement different type of relations between these classes


Sample Example:


//Topic class

class topic{

    // Data members of Topic class

    int ID; 

    char  * Title;     

    char discription[200];


    //Public interface of topic class


    //Default constructor





    //parametrized constructor

    topic(int id, char *title){


    Title=new char[strlen(title)+1];



     //setter function for ID

    void setId() {

    int id;

    cout"\nEnter ID: ";





    void setTitle() {

     char pChar[50];

     coutendl"\nEnter Title: ";


     Title=new char[strlen(pChar)+1];




    void setTitle(char * title){




    void setdiscription(){

        cout"\nplease enter discription of title"endl;





    int getId(){

     return ID;



    char * getTitle(){

       return Title;



    void add(){


        cout"\nAdding new information in add method";






   bool select(){

        cout"Topic selection Area:"endl;

        int select;

        if (select==1)

        cout"\nTopic is selected"endl;


        cout"\nTopic is not selected"endl;



    int search(){

        cout"In Search Mehtod:"endl;

       int found=0;

       if (found)

                        return 1;


                        return 0;



    void View() {

        cout"Viewing the Information";


        cout"\nTitle is:" Title ;

        coutendl"\nDescription is:"discription[100];




    void print(){


        coutendl"\nPrinting the Information:"endl;





    void download(){


        cout"\nDownloading the information:"endl;

        cout"Downloading under processing, Please wait:"endl;

        cout"You are downloding the following:"endlTitle"file";

        cout" and the following discription"endldiscription"File";





    void remove(){


        cout"\nDeleting the information"endl;


        delete []Title;

        delete [] discription;










class SubTopic: public topic {  

     int SubID;

     char * title;

     char discription[100];




         void setSubID(){

             int subid;

             cout"Enter ID of Sub topic:";




         void setdiscription(char []){

             char dChar[200];

             cout"Enter discription of Sub topic:"endl;




         int getSubID(){

             return SubID;



        void setTitle(){

             char pChar[50];

             char dChar[200];

             coutendl"Enter Title : ";


             coutendl"Enter Title discription:";



             cout"Eligible for being a topic"endl;




             cout"Title just contains name and no description"endl;
