Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key principles?Encapsulation, inheritance, and polymorphism are central to OOP
2. What is the core benefits?Enhances code reusability, modularity, maintainability, and scalability
3. Why do programmers use objects instead of just instructions?Objects let programmers make small, independent parts that can be changed without breaking the whole program, making big projects easier to manage.
4. How did object-oriented programming start?The idea began in the 1960s with a language called Simula that added classes and inheritance, and it grew into a full programming style with Smalltalk in the 1970s.

Object: An instance of a class, containing state (attributes) and behavior (methods).
Class: A blueprint or template defining the structure and behavior of objects.
Inheritance: The mechanism by which a new class acquires properties and behaviors from an existing class.
Polymorphism: The ability of objects of different classes to respond to the same method call in their own way.
