Preface to the Second Edition
I never thought that the first edition of this book would sell so long. But now, after twelve years, it’s
time for a new edition that covers C++11, the new C++ standard.
Note that this means more than simply adding new libraries. C++ has changed. Almost all typical
applications of parts of the library look a bit different now. This is not the result of a huge language
change. It’s the result of many minor changes, such as using rvalue references and move semantics,
range-based for loops, auto, and new template features. Thus, besides presenting new libraries and
supplementary features of existing libraries, almost all of the examples in this book were rewritten
at least partially. Nevertheless, to support programmers who still use “old” C++ environments, this
book will describe differences between C++ versions whenever they appear.
I learned C++11 the hard way. Because I didn’t follow the standardization as it was happening I
started to look at C++11 about two years ago. I really had trouble understanding it. But the people
on the standardization committee helped me to describe and present the new features as they are
intended to be used now.
Note, finally, that this book now has a problem: Although the book’s size grew from about 800
to more than 1,100 pages, I still can’t present the C++ standard library as a whole. The library part
of the new C++11 standard alone now has about 750 pages, written in very condensed form without
much explanation. For this reason, I had to decide which features to describe and in how much
detail. Again, many people in the C++ community helped me to make this decision. The intent was
to concentrate on what the average application programmer needs. For some missing parts, I provide
a supplementary chapter on the Web site of this book, http://www.cppstdlib.com, but you still
will find details not mentioned here in the standard.
The art of teaching is not the art of presenting everything. It’s the art of separating the wheat
from the chaff so that you get the most out of it. May the exercise succeed.
