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 triangleI 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
