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``````
