What does class mean in c++

class in C is a user-defined data type that encapsulates data and functions and is used to improve the modularity, reusability and maintainability of code. Class consists of data members, member functions, constructors and destructors. It provides data encapsulation, information hiding, code reuse and scalability.

What is class

In C, class is a user-defined data type used for Encapsulate related data and functions together. It provides data abstraction and information hiding, thereby improving code modularity, reusability, and maintainability.

Components of class

A class is mainly composed of the following parts:

• Data members: class medium Contains data fields. They represent the state of the class.
• Member functions: operations and methods in class. They are used to process class data.
• Constructor: Special member function called when creating a class object, used to initialize the object.
• Destructor: Special member function called when destroying a class object, used to release the resources occupied by the object.

The role of class

class has the following functions:

• Data encapsulation: Combine data and Operations are encapsulated together, protecting internal data from external access.
• Information hiding: Only expose the necessary interfaces of the class and hide the internal implementation details.
• Code reuse: Allows the creation of multiple objects with the same structure and behavior.
• Extensibility: Members of a class can be easily added or modified to make the program more extensible.
