Multi-level Inheritance in C++

In "Multi-level Inheritance" their at least three different classes.

Basically in this type of inheritance a class is derived from a Parent class then an another class is derived from the previously derived class. So their are levels of inheritance occurred. To understand it better see the "Block-Diagram" below.

Block-Diagram

Syntax:-

class Parent1
{
//Body of the Parent1 class
};
class Parent2 : access_specifier Parent1
{
//Body of the Parent2 class
};
class Child : access_specifier Parent2
{
//Body of the Child class
};

Example of Multi-level Inheritance

#include<iostream>
using namespace std;

class Parent1
{
 protected:
  int a=10;
}; 
//Parent2 is derived from Parent1
class Parent2 : public Parent1
{
 protected:
  int b=8;
};
//Child is derived from Parent2
class Child : public Parent2
{
 public:
  int c=12;
                //Child class have all the properties of Parent1 & Parent2
  void put()
  {
   cout<<"Sum is "<<a+b+c;
  }
};


int main()

{
 Child x; //Object of Child class
 x.put();
}
