What is Object-Oriented Programming?
Object-oriented programming (OOP) is a style of writing code like procedural programming,but instead of focusing on a sequence of instructions, OOP focuses on objects.The object can be any real-world entity, like a car. A car has properties (data) such as color and model and also has functionalities (actions) like accelerating and braking. In OOP, these properties and functionalities are included in an object.

What are the main concepts of OOP?
There are some core concepts in OOP:
- Objects: They are the instances that hold data and methods. They were created by class.
- Class: It is the template in which we defined the properties and methods. Any object created from this class will have the class's properties and functionality.
- Encapsulation: this makes data and methods within an object private, which means protecting them from being directly accessed by other parts of the code.
- Inheritance:This allows you to create new classes (sub-classes) that have the same properties and methods as specific classes (super-classes) without writing the code again.
Why is OOP so popular?
OOP is a popular paradigm for many reasons, including:
- Modular code: Objects make your code easier to implement and maintain.
- Better organization: OOP enables developers to convert complex programs into smaller, manageable units.
- Real-world modeling: An object can be any real-world thing; this makes code more understandable and imaginable.
What are the programming languages that support the OOP paradigm?
There are many programming languages that support the OOP style, like:
- Python (general programming language)
- Java (general programming language)
- C# (general programming language)
Conclusion
OOP is supported in many of the modern programming languages. It is very important. There are other programming paradigms, like functional programming, which we will discuss in the next article.
