Multilevel Inheritance: In this type of inheritance, a derived class is created from another derived class.

A derived class A inherits from base class B, which in turn inherits from base class C

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

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

class fourWheeler: public Vehicle 
{  
    public: 
       fourWheeler() 
    { 
      cout<<"Objects with 4 wheels are vehicles"<<endl; 
    } 
}; 

// sub class derived from two base classes 
class Car: public fourWheeler
{ 
   public: 
     Car() 
     { 
       cout<<"Car has 4 Wheels"<<endl; 
     } 
}; 

// main function 
int main() 
{    
    //creating object of sub class will 
    //invoke the constructor of base classes 
    Car obj; 

    return 0; 
}

Output:

This is a Vehicle
Objects with 4 wheels are vehicles
Car has 4 Wheels
