# Multi Level Inheritance Hackerrank Solution in C++

Multi Level Inheritance Hackerrank Solution in C++. 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

## Multi Level Inheritance Hackerrank Solution in C++

``````#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;
}``````

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. This is called Multi-Level inheritance. (B inherits A and C inherits B.)
