HackerRank C++ Multi Level Inheritance

n 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.

#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;

}
