Inheritance Introduction in C++ HackerRank Solution

Hello Programmers, In this post, you will know how to solve the Inheritance Introduction in C++ HackerRank Solution. This problem is a part of the HackerRank C++ Programming Series.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.

Inheritance Introduction in C++ HackerRank Solutions

Problem

One of the important topics of Object Oriented Programming is Inheritance. Inheritance allows us to define a class in terms of another class, which allows us in the reusability of the code.Check out the code below:

class Triangle{
    public:
        void triangle(){
            cout<<"I am a triangle\n";
        }
};

The class Triangle has a function called triangle(). Now we create a class derived from the base class Triangle called Isosceles.

class Isosceles : public Triangle{
    public:
        void isosceles(){
            cout<<"I am an isosceles triangle\n";
        }
};

Now we can create a derived class object and use it to access the functions of the base class.

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

This code will print:

I am an isosceles triangle
I am a triangle

Now write a function in Isosceles class such that the output is as given below.

Sample Output :

I am an isosceles triangle
In an isosceles triangle two sides are equal
I am a triangle
