Introduction

---

Computers, programs, and algorithms are three closely related topics that deserve your attention before you start learning about C++ proper. Why? Simply put, computers execute programs, and programs implement algorithms. As a programmer, you will live your life in the world of computers, programs, and algorithms.

As you progress through your studies you will find it extremely helpful to understand what makes a computer a computer, what particular feature makes a computer a truly remarkable device, and how one functions from a programmer’s point of view. You will also find it helpful to know how humans view programs and how a human readable program is translated into a computer executable form. Lastly, it will be imperative for you to thoroughly understand the concept of an algorithm and how good and bad algorithms ultimately affect program performance.
