Hierarchical Inheritance

Definition:

In this type of inheritance, more than one subclass is inherited from a single base class. i.e. more than one derived class is created from a single base class.

Example:

    // C++ program to implement
    // Hierarchical Inheritance
    #include <iostream>
    using namespace std;

    // base class
    class Vehicle {
       public:
	      Vehicle() { cout << "This is a Vehicle\n"; }
    };

   // first sub class
   class Car : public Vehicle {
   };

   // second sub class
  class Bus : public Vehicle {
  };

  // main function
  int main()
  {
	// Creating object of sub class will
	// invoke the constructor of base class.
	Car obj1;
	Bus obj2;
	return 0;
  }
