Often, a problem is only fully understood through the process of programming a solution for it. This book is for someone who has never programmed before but is willing to work hard to learn. My aim is for you to gain sufficient knowledge and experience to perform simple useful programming tasks using the best up-to-date techniques.
How long will that take? As part of a first-year university course, you can work through this book in a semester assuming that you have a workload of four courses of average difficulty. Also, all learning is gradual: each chapter introduces new useful concepts and illustrates them with examples inspired by real-world uses.
Why would you want to program? Our civilization runs on software. When I talk about programming, I think of the whole spectrum of computer programs from personal computer applications with GUIs graphical user interfaces , through engineering calculations and embedded systems control applications such as digital cameras, cars, and cell phones , to text manipulation applications as found in many humanities and business applications.
However, thanks to feedback from the computer, programming is more concrete than most forms of math, and therefore accessible to more people. Finally, programming can be great fun. This is not the easiest book on beginning programming; it is not meant to be. I just aim for it to be the easiest book from which you can learn the basics of real-world programming. My fundamental assumption is that you want to write programs for the use of others, and to do so responsibly, providing a decent level of system quality; that is, I assume that you want to achieve a level of professionalism.
Consequently, I chose the topics for this book to cover what is needed to get started with real-world programming, not just what is easy to teach and learn. If you need a technique to get basic work done right, I describe it, demonstrate concepts and language facilities needed to support the technique, provide exercises for it, and expect you to work on those exercises.
If you just want to understand toy programs, you can get along with far less than I present. If your desire is to use the work of others without understanding how things are done and without adding significantly to the code yourself, this book is not for you. If so, please consider whether you would be better served by another book and another language. If that is approximately your view of programming, please also consider from where you got that view and whether it in fact is adequate for your needs.
People often underestimate the complexity of programming as well as its value. I would hate for you to acquire a dislike for programming because of a mismatch between what you need and the part of the software reality I describe.
This book is aimed to serve those who do want to write or understand nontrivial programs. If you fit into one of those categories, I refrain from guessing how long it will take you to read this book, but I do encourage you to do many of the exercises. This will help you to counteract the common problem of writing programs in older, familiar styles rather than adopting newer techniques where these are more appropriate. Programming is learned by writing programs.
