Inheritance Introduction in C++ - Hacker Rank Solution
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
