Object-Oriented

In Object-Oriented Programming (OOP), a class is the primary mechanism through which encapsulation is implemented. A class allows the bundling of data (attributes) and methods (functions) that operate on that data, controlling access to them. Through encapsulation, data can be kept private within a class and accessed only through public methods, maintaining a clear boundary between an object's internal state and external interaction.

In Object-Oriented Programming, inheritance represents a hierarchical relationship of generalization, where a subclass (child class) inherits the properties and behaviors of a superclass (parent class). This allows for a "is-a" relationship, where subclasses can be seen as more specific versions of the superclass, sharing common attributes and methods while potentially adding new ones or overriding existing ones.

In Object-Oriented Programming, polymorphism is the ability of an object to take on multiple forms. It allows objects of different classes to be treated as objects of a common superclass, particularly through method overriding (runtime polymorphism) or method overloading (compile-time polymorphism). This flexibility enables a single interface to represent different underlying forms (data types).

The behavior of an object in object-oriented programming is represented by its member functions (or methods), which define the actions the object can perform. Member functions encapsulate the logic that allows the object to interact, respond to messages, or carry out operations based on its current state.

Data members, on the other hand, represent the state of the object, not its behavior.

Abstraction is the object-oriented programming concept that hides complex implementation details and provides a simplified interface for interacting with objects. It allows users to focus on essential features while hiding unnecessary complexity.

While encapsulation is also related to hiding data within an object, abstraction specifically focuses on simplifying interactions by exposing only what is necessary for the user.

Procedure Oriented Programming (POP) is a programming technique that focuses on a sequence of well-defined steps or procedures to solve a problem. It organizes code into functions or procedures, which perform specific tasks, and is structured in a linear way to carry out instructions in a step-by-step manner.

Object-Oriented Programming (OOP) is a programming paradigm that organizes code as a collection of interactive objects. Each object represents an instance of a class and contains both data (attributes) and functions (methods) that operate on the data, allowing for modular, reusable, and interactive program design.
