What is a posible benefit of object-oriented programming?

The benefit of code reusability and easier maintenance is a fundamental advantage of object-oriented programming (OOP). In OOP, concepts such as inheritance and encapsulation allow developers to create classes that can be reused across different parts of a program or even in different programs. This means that instead of writing the same code multiple times, programmers can define a class once and instantiate it wherever needed.

Additionally, because OOP encourages the use of small, modular components, updating or maintaining code becomes more manageable. If a bug is found or a feature needs enhancement within a class, changes can often be made with minimal impact on other parts of the program, promoting a smoother workflow and reducing the potential for introducing new errors.

This contrasts with the notion of having to write all code from scratch, which is inefficient and counterproductive, or the idea that data must be entirely separate from functions, as OOP promotes a close relationship between data and the functions that manipulate it via methods. Lastly, while OOP can aid in user interface design, its benefits span the entire codebase rather than being limited to the interface alone.
