Given the following segments of code, add the following: A default constructor for Class A o Class B A copy constructor for: o Class A Class B Write a main function to test class B o Show that class B inherits functions from class A o Also, show that class B has functions of its own CLASS A class A int getValuca0 const retum valuca: void setvaluea(int x) valaca ladd a default constructor Madd a copy constructor CLASS B class B: public A public: int getValuebo const return valueb: 1 void set Valueb (int x) valueb x; ladd a default constructor lladd a copy constructor private:

Explanation / Answer

PROGRAM CODE:

#include <iostream>

using namespace std;

class A
{
   public:
   //default constructor for initializing values
   A(){valuea = 0;}
   //copy constructor - copies the values of other object
   A(A &other){valuea = other.getValuea();}
   int getValuea() const{return valuea;}
   void setValuea(int x){valuea = x;}
  
   private:
   int valuea;
};

class B : public A
{
   public:
   //default constructor for initializing values
   B(){valueb = 0;}
   //copy constructor - copies the values of other object
   B(B &other):A(other)
   {valueb = other.getValueb();}
   int getValueb() const{return valueb;}
   void setValueb(int x){valueb = x;}
  
   private:
   int valueb;
};

int main(void) {
   B b;
   b.setValueb(5);
   b.setValuea(10);
   B b1(b);
   //prints the value of b
   cout<<"Value of b: "<<b1.getValueb()<<endl;
   //prints the value of a - this is posssible because of inheritance
   cout<<"Value of a: "<<b1.getValuea()<<endl;
   return 0;
}
