Problem Statement - 02B-2016

Observe the following C++ code and answer the questions (i) and (ii). Assume all necessary files are included:

class FICTION
{
  long FCode;
  char FTitle[20];
  float FPrice;
public:
  FICTION() //Member Function 1
  {
    cout<<”Bought”<<endl;
    FCode=100;strcpy(FTitle,”Noname”);FPrice=50;
  }
  FICTION(int C,char T[],float P) //Member Function 2
  {
    FCode=C;
    strcpy(FTitle,T);
    FPrice=P;
  }
  void Increase(float P) //Member Function 3
  {
    FPrice+=P;
  }
  void Show()           //Member Function 4
  {
    cout<<FCode<<”:”<<FTitle<<”:”<<FPrice<<endl;
  }
  ~FICTION()            //Member Function 5
  {
    cout<<”Fiction removed!”<<end1;
  }
};
void main()                          //Line 1
{                                    //Line 2
  FICTION F1,F2(101,”Dare”,75);      //Line 3
  for (int I=0;I<4;I++)              //Line 4
  {                                  //Line 5
    F1.Increase(20);F2.Increase(15); //Line 6
    F1.Show();F2.Show();             //Line 7
  }                                  //Line 8
}                                    //Line 9

(i) Which specific concept of object oriented programming out of the following is illustrated by Member Function 1 and Member Function 2 combined together?
– Data Encapsulation
– Data Hiding
- Polymorphism
– Inheritance

(ii) How many times the message ”Fiction removed!” will be displayed after executing the above C++ code? Out of Line 1 to Line 9, which line is responsible to display the message “Fiction removed!”?
