Question

1. In C++ write a program with a base class thet has a pure virtual function SALARY, and two derived classes. In the first derived class salary is increased by 20%, in the second derived class salary is increased by 30%

Answer 1

#include <iostream>
using namespace std;

class Base //Abstract base class
{
public:
float salary;
   Base()
   {
      cout<<"Enter the initial salary "<<endl;
      cin>>salary;
   }
   virtual void SALARY() = 0; //Pure Virtual Function
};

class Derived:public Base
{
public:
void SALARY()
{
    salary = salary+(salary*20/100);
    cout<<salary;
}
};

class Derived1:public Base
{
public:
void SALARY()
{ salary = salary+(salary*30/100);
    cout<<salary;
}
};

int main()
{

  
Base *b; //creating objects
Derived d;
b = &d; //assigning the address of derived class object to base class pointer
cout<<"Salary after incrementation"<<endl;
b->SALARY(); //calls the derived class SALARY function whose address is assigned to Base class pointer.

return 0;
