The three pillаrs оf оbject-оriented progrаmming (OOP) аre encapsulation, inheritance, and polymorphism. In your own words: Define each pillar (2-3 sentences per pillar) and provide a simple example (e.g., from everyday life or a code snippet in a language like Java or Python). Explain the relationships among them: How does encapsulation serve as a foundational support for inheritance? How does inheritance, in turn, enable or support polymorphism? Discuss why this hierarchy is important for effective OOP design (e.g., in terms of code reusability, maintainability, or flexibility).
