Question

Observe the following C++ code and answer the questions (i) and (ii).

Note: Assume all necessary files are included.

class FIRST
{
   int Numl;
public:
    void Display()
    {
        cout<<Numl<<endl;            //Member Function 1
    }
};

class SECOND: public FIRST
{
    int Num2;
public:
     void Display()                //Member Function 2
     {
         cout<<Num2<<endl;
     }
};

Void main()
{
   SECOND S;
   ___________                    // Statement 1
   ___________                    // Statement 2
  
}

 

1) Which Objected Programming features is illustrated by the definition of classes FIRST and SECOND?

2) Write Statement 1 and Statement 2 to execute Member Function 1 and Member Function 2 respectively using the object S

Answer 1

1) Single Inheritance

2) S.display ();

S.First :: display ();
