About the Author

To Janet, the love of my life.

I find it very strange that only a single name appears on the cover of any book, but especially a book like this. In reality, many people contribute to the creation of a For Dummies book. From the beginning, acquisitions editor Constance Santisteban, project editor Pat O'Brien, and my agent, Claudette Moore, were involved in guiding and molding the book's content. During the development of the seven editions of this book, I found myself hip-deep in edits, corrections, and suggestions from a group of project editors, copyeditors, and technical reviewers this book would have been a poorer work but for their involvement. And nothing would have made it into print without the aid of Suzanne Thomas, who coordinated the first and second editions of the book, Susan Pink, who worked on the third and sixth editions, Katie Feltman who worked on the sixth edition, and Danny Kalev, who did the technical review of the sixth and seventh editions. Nevertheless, one name does appear on the cover and that name must take responsibility for any inaccuracies in the text.

Finally, a summary of the animal activity around my house. For those of you who have not read any of my other books, I should warn you that this has become a regular feature of my For Dummies books.

I moved to the big city in 2005, which meant giving away our dogs Chester and Sadie. I tried to keep our two Great Danes, Monty and Bonnie, but they were just too much for the backyard. We were forced to give them away as well. I married my high school sweetheart in 2011 and moved from Dallas back to my home town of Corpus Christi which meant adopting a new pair of dogs (more like, they adopted me). Jack is a stubborn, black dog of an unidentifiable breed. Scruffy is said to be a wire haired dachshund but you couldn't tell by his appearance as he stays shaved most of the time.

If you are having problems getting started, I maintain a FAQ of common problems at www.stephendavis.com . You can e-mail me questions from there if you don't see your problem. I can't write your program (you don't know how often I get asked to do people's homework assignments), but I try to answer most questions.

Chapter 1

In This Chapter

Finding out about C++

Installing Code::Blocks on Windows, Ubuntu Linux, or Macintosh OS X

Creating your first C++ program

Executing your program

Okay, so here we are: No one here but just you and me. Nothing left to do but get started. Might as well lay out a few fundamental concepts.

A computer is an amazingly fast but incredibly stupid machine. A computer can do anything you tell it (within reason), but it does exactly what its told nothing more and nothing less.

Perhaps unfortunately for us, computers dont understand any reasonable human language they dont speak English either. Okay, I know what youre going to say: Ive seen computers that could understand English. What you really saw was a computer executing a program that could meaningfully understand English.
