Problem Statement
What are the benefits of polymorphism in software design?
Explanation
Polymorphism enables flexibility and scalability in code by allowing objects of different types to be treated uniformly through a common interface. It supports extendability—new subclasses can be introduced without modifying existing code. It enhances maintainability by decoupling code from specific implementations, and encourages use of interchangeable components. Mentioning how polymorphism underpins design patterns and frameworks helps in interview discussions.
