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
