define class and functions.why functions are written inside class.what is the role of a class

Question

Accepted Answer

A class is a blueprint for creating objects that have properties and methods. Functions are written inside a class to define its behavior.

A class is a user-defined data type that encapsulates data and functions that operate on that data.
Functions written inside a class are called methods and are used to define the behavior of the class.
The role of a class is to provide a template for creating objects that share common properties and behavior.
Classes allow for code reusability and organization, making it easier to maintain and modify code.
Example: A class called 'Car' can have properties like 'color' and 'model' and methods like 'start_engine' and 'accelerate'.
