What is object oriented programming : Object-oriented programming (OOP) is a programming paradigm that focuses on creating modular, reusable, and scalable code by treating data as objects that have properties (attributes) and behaviors (methods). It promotes the concept of organizing code into self-contained objects that interact with each other to achieve desired functionality.

Object oriented programming concepts - OOPS concepts : OOPS concepts are the fundamental principles of object-oriented programming. They include four main concepts: encapsulation, abstraction, inheritance, and polymorphism. These concepts provide a structured approach to designing and implementing code to ensure code reusability, modularity, and maintainability.

What are classes : In object-oriented programming, a class is a blueprint or a template that defines a data structure and behavior for objects of that class. It encapsulates attributes (data members) and behaviors (member functions or methods) that define the characteristics and actions of objects created from that class.

What are Objects : In object-oriented programming, an object is an instance of a class. It represents a real-world entity or concept and encapsulates both data (attributes) and functionalities (methods). Objects can interact with each other, communicate, and perform operations based on their defined behaviors and properties.

What is Encapsulation : Encapsulation is an object-oriented programming concept that combines data and methods within a single unit called an object. It involves hiding the internal details of an object and exposing only necessary information and functionalities through well-defined interfaces. Encapsulation facilitates data protection and code modularity, enhancing code maintainability and reusability.

What is Data Abstraction : Data abstraction is an OOP principle that focuses on hiding unnecessary implementation details and exposing only essential and relevant information to the users. It provides a simplified interface for interacting with objects by separating the implementation from the interface. Data abstraction helps in managing complexity, improving code readability, and promoting code reusability.

What is Inheritance : Inheritance is a key principle in object-oriented programming that allows the creation of new classes by inheriting properties and behaviors from existing classes. It enables code reuse and promotes hierarchical relationships between classes. Subclasses (derived classes) inherit characteristics from superclasses (base classes), facilitating the organization and structuring of code.

What is Polymorphism : Polymorphism is an OOP concept that allows objects of different classes to be treated as objects of a common parent class. It enables the same interface or method to exhibit different behaviors in different contexts or classes. Polymorphism promotes code flexibility, modularity, and extensibility, as it allows objects to be dynamically bound or resolved at runtime based on their specific implementations.
