An *object* is an entity that contains data and procedures to manipulate them. Similar to how each variable has a *type* of data associated to it, each object has a *class* associated to it, which describes the properties of the the objects: its data (*attributes*), and the procedures that can be used to manipulate its data (*methods*).

A class is a description of the data and processes of an object. The class’ declaration establishes the attributes that each of the objects of the class will have, and the methods that it can invoke.

An object is an entity that contains data (same as a variable), called its `attributes`, and it also contains procedures, called `method`, that are used to manipulate them. The objects are "instances" of a class that are created in a similar manner as how variables are defined:

The methods of a class determine the actions that we can take on the objects of that class. The methods are similar to functions in the sense that they can receive parameters and return a result. An elementary way to know the methods of a class is reading the class declaration. For example, the following is a section of the declaration of the class `Bird` in the file `bird.h`.
