Provides a solid introduction to computer science that emphasizes software engineering and the development of good programming style. Covers the language of C. Paper. DLC: C (Computer program language)
Welcome! By picking up this book, you have taken a step into the world of computer science - a field of study that has grown from almost nothing half a century ago to become one of the most vibrant and active disciplines of our time.
Over that time, the computer has opened up extraordinary possibilities in almost every area of human endeavor. Business leaders today are able to manage global enterprises on an unprecedented scale because computers enable them to transfer information anywhere in a fraction of a second. Scientists can now solve problems that were beyond their reach until the computer made the necessary calculations possible. Filmmakers use computers to generate dramatic visual effects that are impossible to achieve without them. Doctors can determine much more accurately what is going on inside a patient because computers have enabled a massive transformation in the practice of medicine.
Computers are a profoundly empowering technology. The advances we have seen up to now are small compared to what we will see in the next century. Computers will play a major role in shaping that century, just as they have the last 50 years. Those of you who are students today will soon inherit the responsibility of guiding that progress. As you do so, knowing how to use computers can only help.
Like most skills that are worth knowing, learning how computers work and how to control their enormous power takes time. You will not understand it all at once. But you must start somewhere. Twenty-five centuries ago, the Chinese philosopher Lao-tzu observed that the longest journey begins with a single step. This book can be your beginning.
For many of you, however, the first step can be the hardest to take. Many students find computers overwhelming and imagine that computer science is beyond their reach. Learning the basics of programming, however, does not require advanced mathematics or a detailed understanding of electronics. What matters in programming is whether you can progress from the statement of a problem to its solution. To do so, you must be able to think logically. You must have the necessary discipline to express your logic in a form that the computer can understand. Perhaps most importantly, you must be able to see the task through to its completion without getting discouraged by difficulties and setbacks. If you stick with the process, you will discover that reaching the solution is so exhilarating that it more than makes up for any frustrations you encounter along the way.
This book is designed to teach you the fundamentals of programming and the basics of C, which is the dominant programming language in the computing industry today. It treats the whys of programming as well as the hows, to give you a feel for the programming process as a whole. It also includes several features that will help you focus on the essential points and avoid errors that slow you down. The next few pages summarize these features and explain how to use this book effectively as you begin your journey into the exciting world of computer science.
