What is the term for a function that is a member of a class?

A function that is a member of a class is specifically referred to as a method. In object-oriented programming, classes are blueprints for creating objects and methods are the functions that define the behaviors of those objects. Methods typically operate on data contained within the class, allowing for encapsulation of both data and behaviors in a structured way.

This distinction is important because it highlights the role of methods in object-oriented design. They not only help in organizing code but also enable objects to interact with each other and manipulate their internal state. Understanding the term "method" in this context is crucial for grasping object-oriented programming concepts effectively.

The other choices represent different programming concepts. A procedure generally refers to a routine or subroutine that may or may not be associated with a class. An attribute is more closely related to data members or properties of a class rather than functions. An object refers to an instance of a class, where the class provides the definition, but it does not represent a function itself.
