If you’ve always wanted to learn how to program a computer, or to learn the widely used C++ programming language in particular, C++ Without Fear, Second Edition, offers an ideal way to get you started.
Written with the same approach that earned the first edition rave reviews, the author first emphasizes short, simple examples that are easy to enter; then, within a couple of chapters, he has you creating useful utilities, playing games, and using the computer to solve interesting puzzles. His approach is a welcome departure from many programming texts, which quickly get bogged down in complex and sometimes meaningless examples. You’ll find here, patiently explained and clearly illustrated, everything you need to learn programming quickly, and to have fun doing it!
Yes, programming can be a complex task, and C++ is a language often used by professionals. In fact, many of the coolest games, graphics, and Internet applications are created with C++, and it’s even been used on the Mars rovers. But the language, like the monster pictured on the cover, need not be all that fearsome. Broken down to its essentials, and enhanced by simple examples, practical exercises, and the whys and tricks behind each language feature, you’ll be amazed at the rapid progress you can make.
With C++ Without Fear, Second Edition, you will
NEW AND IMPROVED
While compatible with nearly every version of the C++ language, this second edition has been updated to cover important features of the newest and greatest C++ standard (C++0x). In addition, it now includes
Whether you wish to learn C++ programming for pleasure, or you’re considering a career in programming, this book is an outstanding choice.
C++ Software
To run the programs included in this book, and to create your own, you will need a C++ compiler. Some compilers are available commercially, such as Microsoft’s Visual C++. Others are available for free. Although availability changes from time to time, as we went to press, a free compiler for Windows may be downloaded from the following website, using the instructions given there:
http://csjava.occ.cccd.edu/~gilberts/devcpp5/
Please note that, whereas the book is intended to be compatible with a wide range of standard C++ compilers, we cannot guarantee compatibility with every compiler you might come across, especially older ones. Nor can we guarantee that the compiler linked to above is free from defect. The link is provided simply as a good place to start in your search for a compiler that works for you, and one that doesn’t cost anything.
