This document provides an introduction to object-oriented programming in C++. It explains that object orientation involves breaking programs into self-contained objects defined by classes. A class defines the variables and functions of an object, while an object is an instance of a class. The document uses examples like a Car class to demonstrate how to define classes with header and implementation files, and create objects from classes in a main program. It notes that object orientation can make programs easier to understand and reuse code through breaking problems into objects.
