  2. What is OOP? Object-Oriented Programming (OOP) is . It organizes code by combining data (attributes) and the methods (functions) that operate on that data into objects. Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behavior.

  3. Four Pillars of OOPS Encapsulation: Bundling data and methods within an object, protecting data from outside interference. Inheritance: Allows a class to inherit properties and methods from another class, promoting code reuse and establishing hierarchical relationships. Polymorphism: The ability of objects to take on many forms, allowing different objects to respond to the same method call in their own way. Abstraction: Simplifying complex systems by modeling essential properties and behaviors while hiding unnecessary details.

  4. Common Interview Questions Define each OOP pillar with examples Difference between abstraction & encapsulation Runtime vs compile-time polymorphism Why method overriding? Access specifiers & inheritance effects Constructor vs destructor Final/static/abstract method distinctions
