"Computer programming is a powerful tool for children to 'learn learning,' that is, to learn the skills of thinking and problem-solving...Children who engage in programming transfer that kind of learning to other things."--Nicholas Negroponte, the man behind the One Laptop Per Child project that hopes to put a computer in the hands of every child on earth, January 2008 Your computer won't respond when you yell at it. Why not learn to talk to your computer in its own language? Whether you want to write games, start a business, or you're just curious, learning to program is a great place to start. Plus, programming is fun! Hello World! provides a gentle but thorough introduction to the world of computer programming. It's written in language a 12-year-old can follow, but anyone who wants to learn how to program a computer can use it. Even adults. Written by Warren Sande and his son, Carter, and reviewed by professional educators, this book is kid-tested and parent-approved. You don't need to know anything about programming to use the book. But you should know the basics of using a computer--e-mail, surfing the web, listening to music, and so forth. If you can start a program and save a file, you should have no trouble using this book.
