Each ofthe book's many examples has trapped a professional programmer. In addition to its examples, C Traps and Pitfalls offers adviceon: *avoiding off-by-one errors *understanding and constructing function declarations *understanding the subtle relationship between pointers andarrays Distilled from the author's experience over a decade ofprogramming in C, this book is an ideal resource for anyone,novice or expert, who has ever written a C program. 0201179288B04062001
