Single Inheritance in C++

When a Derived Class to inherit properties and behavior from a single Base Class , it is called as single inheritance.

Syntax of Single Inheritance:

Base_class : access_specifier derived_class

{

       //body of subclass

};

 

Example:

#include<iostream>

using namespace std;

class Parent{   // parent class

    protected:

               int a;

               int b;

               public:

                               Parent(){

                                              a = 10;

                                              b = 20;

                               }

}; 

class Child: public Parent{   // child class

               public:

                               void show(){

                                              cout<< " Value of a= "<<a <<endl;

                                              cout<< " Value of b= "<<b <<endl;

                               }

};       

int main()

{

Child obj;

obj.show();

}

       

Output:

Value of a=10

Value of b=20
