Abstraction in oops or C#

 What is an abstraction in oops or c#?

Abstraction in oops or C# is a fundamental concept in Object-Oriented Programming (OOP) that refers to the idea of representing complex real-world objects or systems in a simplified way, by focusing on the essential features and ignoring the details that are not relevant to the current context.

In other words, abstraction allows us to model a system at a high level of abstraction, where we focus on what an object does, rather than how it does it. Abstraction helps to manage the complexity of a system by hiding unnecessary details and providing a simplified interface for interacting with the system.

Abstraction is often implemented through the use of abstract classes and interfaces. An abstract class is a class that cannot be instantiated and contains one or more abstract methods, which have no implementation and are intended to be overridden by subclasses. Interfaces are similar to abstract classes, but they only contain method signatures and do not have any implementation.

By defining abstract classes and interfaces, we can create a blueprint for classes that will implement them, and provide a common set of methods and properties that can be used to interact with those classes, without having to know the details of how they work.

Abstraction is important in OOP because it promotes modularity, flexibility, and maintainability by allowing us to design systems that are easily extensible and adaptable to changing requirements. By using abstraction, we can create software systems that are easier to understand, test, and modify, which leads to more reliable and efficient code.
