Multiple Inheritance in C++

Multiple Inheritance is a feature of C++ where a class can inherit from more than one classes. i.e one sub class is inherited from more than one base classes.

Syntax:

class Base_class_name : access_mode derived1_class, access_mode derived2 _class

{

   //body of Base_class

}

 

Example:

#include<iostream>

using namespace std;

class Parent{   // Base class

               public:

                               Parent(){

                                              cout<< " This is Parent class " <<endl;

                               }

}; 

class Child1{   //derived1 class --> Base class

               public:

                               Child1(){

                                              cout<< " This is Child1 class " <<endl;

                               }

};

class Child2:public Parent ,public Child1{   //derived2 class --> Base class

               public:

                               Child2(){

                                              cout<< " This is Child2 class " <<endl;

                               }

};       

int main(){                   

     Child2 obj2;

}

Output:

This is Parent class

This is Child1 class

This is Child2 class
