This book is about programming. You can’t learn to program without a way to see what a particular program does when a computer processes it. Setting up a mechanism for observing what a program does is sometimes called creating a test bed.
<BODY> var month_income = new Array(12);
In addition, I’ve added some special graphical features to Learn How to Program to make it easier for you to find the information you need:
You’ll also find the following special icons highlighting important points in the text:
|Way Cool|| |
means, as you’d expect, that this is something real neat and groovy!
|Do It Right!|| |
explains the right way to do something as opposed to a way that merely “works.”
|Try This at Home|| |
highlights fun projects that I encourage you to work out—and extend—on your own.
|Advanced Topic|| |
means, as you’d suspect, that the text marked with this icon is relatively advanced. I’ve included the advanced material because it’s important and for completeness. However, don’t worry if you find it difficult—you can simply move on to the next topic. You can always come back later and reread the Advanced Topic sections when they’ll likely make more sense to you.
By the way, you’ll find the code for all the programs explained in the book on the Apress Web site (http://www.apress.com/) in the Downloads section. But I encourage you not to download the code. You’ll learn much more if you enter it yourself at the keyboard.
