When I went to college, I was taught a more sophisticated approach to programming that uses functions to group statements of code. Functions are great because you can easily organize your code into reusable blocks.

When I started working as a programmer, I encountered yet a third programming paradigm that organizes code into classes. I found this curious because even though a program's basic building block is classes, the style of programming is called object-oriented programming (OOP).

Visual Studio provides many tools that support the activities of object-oriented design (OOD) and programming. This chapter covers some of the basics of working with objects and classes and shows you how to use Class Designer to visually design and inspect classes and objects.

Bringing Programs to Life the Object-Oriented Way

Most programmers take awhile to figure out the relationship between objects and classes when they first encounter OOP. If you think of software as a means of modeling a real-world scenario, the following points are worth remembering:
