What does object-oriented mean?

• A. Programs organized by functions only.
• B. Programs interpreted line-by-line without objects.
• C. Programs are organized around objects representing instances of classes.
• D. Programs compiled to machine code before execution.

Answer: (C)

Object-oriented programming models software as a set of objects that represent real things or concepts, each object being an instance of a class and encapsulating its own data and behavior. This organization centers on creating objects, defining their properties and methods, and letting them interact to perform tasks. The key idea is that code is built around these objects and their interactions, not simply around a sequence of functions or steps. So describing programs as being organized around objects that are instances of classes captures the essence of object-oriented programming. The other statements describe different ideas—the first points to a purely procedural style that focuses on functions; the second emphasizes an execution model that ignores objects; and the last talks about how code is built (compiled) rather than how it’s structured or modeled.
