My work at Microsoft gave me the unique experience of working on large software projects and applying and developing state of the art design and programming methodologies. Of course, there are plenty of books on the market that talk about design, programming paradigms, languages, etc. Unfortunately most of them are either written in a dry academic style and are quite obsolete, or they are hastily put together to catch the latest vogue. There is a glut of books teaching programming in C, C++ and, more recently, in Java. They teach the language, all right, but rarely do they teach programming.

Optimizing C++ provides working programmers and those who intend to be working programmers with a practical, real-world approach to program optimization. Many of the optimization techniques presented are derived from my reading of academic journals that are, sadly, little known in the programming community. This book also draws on my nearly 30 years of experience as a programmer in diverse fields of application, during which I have become increasingly concerned about the amount of effort spent in reinventing optimization techniques rather than applying those already developed.

Whether you are using this book on your own or in school, there are many good reasons to learn how to program. You may have a problem that hasn't been solved by commercial software; you may want a better understanding of how commercial programs function so you can figure out how to get around their shortcomings and peculiarities; or perhaps you're just curious about how computers perform their seemingly magical feats. Whatever the initial reason, I hope you come to appreciate the great creative possibilities opened up by this most ubiquitous of modern inventions.

In order to use Solaris and most other Unix Systems you will need to be familiar with the Common Desktop Environment (CDE). Before embarking on learning C with briefly introduce the main features of the CDE. Most major Unix vendors now provide the CDE as standard. Consequently, most users of the X Window system will now be exposed to the CDE. Indeed, continuing trends in the development of Motif and CDE will probably lead to a convergence of these technologies in the near future. This section highlights the key features of the CDE from a Users perspective.
