Question

The class MusicPlayer represents a portable electronic system with headphones. Consider the class diagram shown below. Each instance of a MusicPlayer has a brand, price and capacity associated with it. For the constructor shown below, here is the class definition:

Based on the information shown here, a possible implementation (.cpp) for MusicPlayer is shown below.

myBrand = b;
myPrice = p;
myCapacity = c;

return( myBrand );

myBrand = brand;

return( myPrice );

myPrice = price;

return(myCapacity);

myCapacity = capacity;

Consider the following instance information.

IPod mine; // by default, has a brand of "Apple IPod"
// a price of 249.99 and a capacity of // 10,000 songs
IPod hp( 150.00, 1000, "Hewlett-Packard IPod" );
// this instance has a brand of "Hewlett-Packard IPod",
// a price of 150.00 and a capacity of 1,000 songs

TO RECEIVE FULL CREDIT, YOUR IPOD CONSTRUCTOR MUST CALL THE PARENT-CLASS MUSICPLAYER CONSTRUCTOR.

Class Diagram Class Definition (.h file) MusicPlayer MusicPlayer( string brand, double price, int capacity );

string getBrand() const;
void setBrand( string brand );
double getPrice() const;
void setPrice( double price );
int getCapacity() const;
void setCapacity( int capacity ); std::string myBrand;
int myCapacity;
double myPrice; class MusicPlayer {
public:

MusicPlayer(string b,double p,int c);

std::string getBrand() const;
void setBrand( std::string brand );
double getPrice() const;
void setPrice( double price );
int getCapacity() const;
void setCapacity( int capacity );

private:
std::string myBrand;
double myPrice;
int myCapacity;
};

Explanation / Answer

//Program:

//Ipod.h

#ifndef Ipod_h
#define Ipod_h
#include "MusicPlayer.h"
class IPod : public MusicPlayer

   public:
   IPod();
   IPod(double p,int c,string b);
};
#endif
-----------------------------------------------
//Ipod.cpp
#include "Ipod.h"

//default constructor passes parameter to base class
IPod::IPod()::MusicPlayer("Apple IPod",249.99,10000);
{}

//parameterized constructor passes parameter to base class
IPod(double p,int c,string b)::MusicPlayer(b,p,c)
{}

-----------------------------------------------------
//MusicDriver.cpp contains main()
#include <iostream>
#include "Ipod.h"
#include "MusicPlayer.h"
int main()
{
   //instance information
   MusicPlayer Walkman("Sony Walkman",99.99, 10);
   cout<<endl<<"Walkman"<<endl;
   cout<<" Brand Name:"<<Walkman.getBrand()<<endl;
   cout<<" Price:"<<Walkman.getPrice()<<endl;
   cout<<" Capacity:"<<Walkman.getCapacity()<<endl;
   //Ipod
   // by default, has a brand of "Apple IPod"
   // a price of 249.99 and a capacity of // 10,000 songs
   IPod mine;
   cout<<endl<<"Ipod 1"<<endl;
   cout<<" Brand Name:"<<mine.getBrand()<<endl;
   cout<<" Price:"<<mine.getPrice()<<endl;
   cout<<" Capacity:"<<mine.getCapacity()<<endl<<endl;
   // this instance has a brand of "Hewlett-Packard IPod",
   // a price of 150.00 and a capacity of 1,000 songs
   IPod hp( 150.00, 1000, "Hewlett-Packard IPod" );
   cout<<endl<<"Ipod 2"<<endl;
   cout<<" Brand Name:"<<hp.getBrand()<<endl;
   cout<<" Price:"<<hp.getPrice()<<endl;
   cout<<" Capacity:"<<hp.getCapacity()<<endl<<endl;
  
   return 0;
