Write a C++ program for incorporating multi-level inheritance.

AIM: Write a C++ program for incorporating multi-level inheritance.

THEORY:

Inheritance is the process of inheriting properties of objects of one class by objects of another class. The class which inherits the properties of another class is called Derived or Child or Sub class and the class whose properties are inherited is called Base or Parent or Super class. When a class is derived from a class which is also derived from another class, i.e. a class having more than one parent classes, such inheritance is called Multilevel Inheritance. The level of inheritance can be extended to any number of level depending upon the relation. Multilevel inheritance is similar to relation between grandfather, father and child. 

SOURCE CODE:

#include<iostream>

using namespace std;

class A{

            protected:

            char name[20];

            int age;

};

class B:public A{

            protected:

            int h,w;           

};

class C:public B{

            public:

            char g;

            void get_data(){

            cout<<"\n enter name and age:";

            cin>>name>>age;

            cout<<"\n enter weight and height:";

            cin>>w>>h;

            cout<<"\n enter gender:";

            cin>>g;

            }

            void show(){

                        cout<<name<<endl<<age<<endl;

                        cout<<w<<endl<<h<<endl;

                        cout<<g<<endl;

            }

};

int main(){

            C ob;

            ob.get_data();

            ob.show();

}
