Here is an example program to illustrate multilevel inheritance.
// example of multilevel inheritance
// Parent class
#include<iostream>
using namespace std;
class person
{
private:
char name[15], address[15];
public:
void getdata()
{
cout<<"\nEnter Name: ";
cin>>name;
cout<<"\nEnter address: ";
cin>>address;
}
void showdata()
{
cout<<endl<<"Name: "<<name;
cout<<endl<<"Address: "<<address;
}
};
// derived class from parent class Person
class employee:public person
{
private:
int empID;
public:
void getdata()
{
person::getdata();
cout<<"\nEnter employee ID ";
cin>>empID;
}
void showdata()
{
person::showdata();
cout<<endl<<"Employee ID: "<<empID;
}
};
// derived class from parent class person
class manager: public employee
{
private:
char qual[10];
public:
void getdata()
{
employee::getdata();
cout<<"\nEnter qualification: ";
cin>>qual;
}
void showdata()
{
employee::showdata();
cout<<"\nQualification: "<<qual;
}
};
// driver program
int main()
{
manager obj;
obj.getdata();
obj.showdata();
return 0;
}
The output of the program is:
