Challenge Problems

Push your limits with challenges.

Question 1

Consider a library system where books can have different types (e.g., fiction, non-fiction). Design a class for 'Book' with attributes and methods. Then create subclasses for different book types that inherit features from the 'Book' class. Explain how inheritance benefits your design.

💡 Hint: Think about shared features among all books when designing your classes.

Question 2

Create a scenario in which polymorphism improves the usability of your code. For instance, imagine if you had a method 'performAction()' in multiple derived classes with different implementations.

💡 Hint: Consider examples where functions can behave in various ways, depending on the object type.
