Hello coders, today we are going to solve Multi Level Inheritance HackerRank Solution in C++.

Problem
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.
I am an equilateral triangle
I am an isosceles triangle
I am a triangle
Solution – Multi Level Inheritance in C++
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"; } }; //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; }
