Structure of the Problem Requirements
Deriving directly from more than one class is usually called multiple inheritance. The example contains a parent class that is called calculator and they have two methods add() and subtract(). The Parent class has two more child classes which are further inherited.
Source Code
#include <iostream>
using namespace std;
class calculator
{
public:
void add()
{
cout<<"Add method \n\n ";
}
void subtract()
{
cout<<"\n Subtract Method \n\n ";
}
};
class add : public calculator //add class inherited calculator
{
};
class Subtract : public add //subtract class inherited add and further the caluclulotr
{//subtract class be can derived from a derived class which is known as multilevel inhertiance
};
int main()
{
Subtract s;
add a;
cout<<"\n\n\n\t ********** MULTILEVEL INHERITANCE ********** \n\n\n";
a.subtract();
s.subtract();
return 0;
}
