A self-contained entity with its own state and behavior

A function that performs a specific task

A variable that stores data temporarily

A set of instructions executed in sequence

A class is a specific book, and an object is the blueprint for all books.

A class is the blueprint for all books, and an object is a specific book created from that blueprint.

A class and an object are the same thing in programming.

A class is the author, and an object is the book.

Allowing direct access to all internal data of an object

Hiding the internal workings and data of an object from external components

Sharing methods between unrelated objects

Automatically inheriting attributes from another class

A derived class can only inherit methods, not attributes.

Inheritance allows a new class to be created based on an existing class, inheriting all attributes and methods.

Inheritance prevents a class from overriding methods.

A class can only inherit from one parent class.

Overriding allows a derived class to provide its own implementation for a method defined in its parent class.

Overriding is not related to polymorphism.

Overriding replaces the parent's default behavior for a method when invoked on an object of the derived class.

Overriding prevents the use of virtual methods.

A function that performs calculations

A fundamental building block representing a real-world thing or concept

A type of variable that stores only numbers

A process for organizing code into steps

Association is a general relationship, while aggregation and composition are specific, stronger forms of association.

Association means one class is part of another, while aggregation does not.

Aggregation and composition do not involve any interaction between classes, while association does.

Association is only used for inheritance, while aggregation and composition are not.
