Classes are used to define the operations supported by a particular class of objects (its instances). If your application needs to keep track of people, then Person is probably a class; the instances of this class represent particular people you are tracking. Functions are for calculating things.Property (programming) A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method. The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to ' getter ' …The class default access type is private, and the default mode for inheritance is private. A class should be used for grouping data and methods that operate on that data. In short, the convention is to use struct when the purpose is to group data, and use classes when we require data abstraction and, perhaps inheritance.You may also notice that some objects, in turn, will also contain other objects. These real-world observations all translate into the world of object-oriented programming. A software object. Software objects are conceptually similar to real-world objects: they too consist of state and related behavior.

A class name should instantly communicate what the class is. Good names drive good designs. If your problem is what to name exposed internal classes, maybe you should consolidate them into a larger class. If your problem is naming a class that is doing a lot of different stuff, you should consider breaking it into multiple classes.
