Introduction To C++

C++ is a general-purpose programming language that was developed as an enhancement of the C language to include object-oriented paradigm. It is an imperative and a compiled language. 

C++ is a middle-level language rendering it the advantage of programming low-level (drivers, kernels) and even higher-level applications (games, GUI, desktop apps etc.). The basic syntax and code structure of both C and C++ are the same. 

C++ programming language was developed in 1980 by Bjarne Stroustrup at bell laboratories of AT&T (American Telephone & Telegraph), located in U.S.A. Bjarne Stroustrup is known as the founder of C++ language.

Multi Level Inheritance in C++- Hackerrank Solution


Solve the problem 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 we will see what multi-level inheritance is. 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.)

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

Input Output :

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

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

class Triangle
		void triangle()
			cout<<"I am a triangle\n";

class Isosceles : public Triangle
  		void isosceles()
    		cout<<"I am an isosceles triangle\n";
//Write your code here.
/* Multi Level Inheritance in C++ - Hacker Rank Solution START */
class Equilateral : public Isosceles
        void equilateral()
            cout<<"I am an equilateral triangle\n";

/* Multi Level Inheritance in C++ - Hacker Rank Solution END */

int main()
    Equilateral eqr;
    return 0;
