Inheritance Introduction

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

Solution – Inheritance Introduction in C++

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\n";
    	}
  		//Write your code here.
          void description()
  {
          cout<<"In an isosceles triangle two sides are equal\n";
        }
};

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