Abstractions

Abstraction is the process of hiding the complex implementation details and showing only the necessary features of an object. In other words, it helps to reduce programming complexity and effort.

Why Abstraction?

• Reduce Complexity: Abstraction helps to reduce programming complexity and effort.
• Security: It helps to hide the internal details of an object and show only the necessary features of an object.
• Code Reusability: Abstraction helps to reuse the code and use it in multiple places.
• Flexibility: It helps to change the implementation of an object without affecting the rest of the code.

Programming Abstractions

In programming, abstraction is achieved using three main concepts:

1. Data and Variables: Variables are used to store data values. They are used to represent the state of an object. They allow abstracting operations and algorithms from the specific values they operate on.

2. Functions and Methods: Functions and methods are used to define abstract behavior only in terms of inputs and outputs. They also allow abstracting the implementation details of an algorithm.

3. Classes and Objects: Classes and objects are used to define abstract data types. They allow abstracting the data structure and behavior of an object.
