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.)
