Understanding Abstraction in Object-Oriented Programming (OOP)

Abstraction is a fundamental concept in Object-Oriented Programming (OOP) that allows developers to focus on essential details while hiding unnecessary complexity. Here's a concise overview:

What is Abstraction?: Abstraction involves simplifying complex systems by modeling classes based on real-world entities. It allows us to define the structure and behavior of objects without exposing their internal implementation details.

Key Elements of Abstraction:

1. Classes and Objects: Abstraction enables us to create classes representing real-world entities, abstracting away irrelevant details.
2. Interfaces and Abstract Classes: These constructs provide a blueprint for creating concrete implementations, defining contracts without specifying implementation specifics.

Benefits of Abstraction:

1. Modularity: Encourages modular design, making code more manageable and reusable.
2. Encapsulation: Supports encapsulation by hiding internal details, promoting code maintenance and security.
3. Flexibility: Allows for easy modification and extension of code, enhancing scalability.

Code Example in C#:

In this example, the IShape interface abstracts the common behavior of different shapes, allowing us to create concrete implementations for specific shapes like Circle and Rectangle.
