How are data member and member function organized in object oriented program?

In object-oriented programming, data members (attributes) and member functions (methods) are organized within classes. Data members represent the state or properties of an object, while member functions define the behaviors or operations that can be performed on that data. This encapsulation allows for better data management and code organization, enabling objects to maintain their own state while providing functionality through their methods. Classes serve as blueprints for creating objects, ensuring that both data and behaviors are bundled together.
