Multi Level Inheritance.cpp-HackerRank

Problem-Now 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";

        }

};

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;

}
