Single Inheritance in C++

In "Single Inheritance" their is only one base-class and one derived-class.

Basically their is only one "Parent-class"(BASE CLASS) from which  the properties / behavior will be inherited to the "Child-class"(DERIVED CLASS).

Block-Diagram

Syntax:-

class Parent
{
//Body of the Parent class
};

class Child : access_specifier Parent
{
//Body of the Child class
};

Example of Single-Inheritance

#include<iostream>
using namespace std;

class Parent
{
 protected:
  int a=10;
};

class Child : public Parent //Inheriting the class
{
 public:
  int b=2;
  void put()
  {
   cout<<"Sum is "<<a+b;
   //Using 'a' from the Parent class
  }
};

int main()
{
 Child x; //'x' is the object of class "Child"
 x.put(); //Calling the function "put()"
}
