Hierarchical Inheritance in C++

In "Hierarchical Inheritance" their is only one Parent class and 'n' numbers of  Child class.

Basically their is only one Parent class which have a lot of Child class sharing the same properties. This type of inheritance is used when we need to share the same type of behavior / properties / functions to a number of  different classes.

Syntax:-

class Parent
{
//Body of the Parent class
};
class Child1 : access_specifier Parent
{
//Body of the Child1 class
};
class Child2 : access_specifier Parent
{
//Body of the Child2 class
};
class Child3 : access_specifier Parent
{
//Body of the Child3 class
};
class Child4 : access_specifier Parent
{
//Body of the Child4 class
};

Example of Hierarchical Inheritance

#include<iostream>
using namespace std;

class Name
{
 protected:
  char name[20]="Mr C";
};

class Marks:public Name
{
 public:
  int total_marks=90;
  void put()
  {
   cout<< name<<" have got Total marks: "<<total_marks;
   cout<<endl;
  }
};

class Academic_Details:public Name
{
 public:
  int Redg_no=123456;
  void put()
  {
   cout<<name <<" have the Registration number: "<< Redg_no;
  }
};

int main()
{
 Marks x;
 Academic_Details y;
 x.put();
 y.put();
}
