This challenge is an extension of a previous challenge named Inheritance-Introduction. We highly recommend solving Inheritance-Introduction before solving this problem.

In the previous problem, we learned about inheritance and how can a derived class object use the member functions of the base class.

In this challenge, we explore multi-level inheritance. Suppose, we have a class A which is the base class and we have a class B which is derived from class A and we have a class C which is derived from class B, we can access the functions of both class A and class B by creating an object for class C. Hence, this mechanism is called multi-level inheritance. (B inherits A and C inherits B.)

Create a class called Equilateral which inherits from Isosceles and should have a function such that the output is as given below.

Sample Output

I am an equilateral triangle
I am an isosceles triangle
I am a triangle

SOLUTION :-

#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

class Triangle{
    public:
        void triangle(){
            cout<<"I am a triangle\n";
        }
};

class Isosceles : public Triangle{
      public:
          void isosceles(){
            cout<<"I am an isosceles triangle\n";
          }
};

//Write your code here.
class Equilateral : public Isosceles{
    public:
        void equilateral() {
            cout << "I am an equilateral triangle\n";
        }
};

int main(){
  
    Equilateral eqr;
    eqr.equilateral();
    eqr.isosceles();
    eqr.triangle();
    return 0;
}
