HackerRank Inheritance Introduction solution in c++ programming

In this HackerRank Inheritance introduction problem in the c++ programming language, you need to write a function in Isosceles class such that the output is printed in the separated three lines.

HackerRank Inheritance introduction problem solution in c++ programming.

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


class Triangle
{
        public:

            void triangle()
                {
                cout<<"I am a trianglen";
            }
};

class Isosceles : public Triangle
{
        public:

            void isosceles()
                {
                cout<<"I am an isosceles trianglen";
            }

                void description()
                {
                        cout<<"In an isosceles triangle two sides are equaln";
                }
};

int main(){
    Isosceles isc;
    isc.isosceles();
  	isc.description();
    isc.triangle();
    return 0;
}
