OOP (Object-Oriented Programming) is a programming paradigm based on objects and classes to structure software design.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism where a new class inherits properties and behavior from an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to present the same interf...read more
