What is the primary function of a class?

The primary function of a class is to specify properties for all objects of that class. A class serves as a blueprint for creating objects, defining the characteristics (or properties) and behaviors (or methods) that those objects will have. When you define a class, you establish a structure that dictates how the objects instantiated from that class will function and what attributes they will possess.

For example, if you create a class called "Car," you might specify properties such as "color," "make," "model," and "year." Each object created from the "Car" class will have these properties, allowing you to create distinct car objects with specific values for those properties. This encapsulation of data and behavior is a fundamental aspect of object-oriented programming, making classes essential for organizing code and promoting reusability.

The other choices relate to aspects of programming that are not directly tied to the core purpose of a class. Managing memory, handling exceptions, and writing data to a file are separate concerns within software development that may involve classes, but they do not define the class itself or its primary role in the context of object-oriented programming.
