PREFACE
In computing, turning the obvious into the useful is a
living definition of the word "frustration.*
In the years since the First edition of C Programming: A Modem Approach was
published, a host of new C-based languages have sprung up—Java and C# foremost
among them—and related languages such as C++ and Perl have achieved greater
prominence. Still, C remains as popular as ever, plugging away in the background,
quietly powering much of the world‟s software. It remains the linguafranca of the
computer universe, as it was in 1996.
But even C must change with the times. The need for a new edition of C Pro-
gramming: A Modem Approach became apparent when the C99 standard was pub-
lished. Moreover, the first edition, with its references to DOS and 16-bit processors,
was becoming dated. The second edition is fully up-to-date and has been improved in
many other ways as well.
What‟s New in the Second Edition
Here‟s a list of new features and improvements in the second edition:
■ Complete coverage of both the C89 standard and the C99 standard. The biggest
difference between the first and second editions is coverage of the C99 standard.
My goal was to cover every significant difference between C89 and C99,
including all the language features and library functions added in C99. Each C99
change is clearly marked, either with “C99” in the heading of a section or—
f*ffifr in the case of shorter discussions—with a special icon in the left margin. I
did this partly to draw attention to the changes and partly so that readers who
aren‟t interested in C99 or don‟t have access to a C99 compiler will know what
to skip. Many of the C99 additions are of interest only to a specialized audience,
but some of the new features will be of use to nearly all C programmers.
