   Inheritance Introduction
   
   

Objective

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

Solution  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\nIn an isosceles triangle two sides are equal\n";

        }

};

int main(){

    Isosceles isc;

    isc.isosceles();

      //isc.description();

    isc.triangle();

    return 0;

}
