This work presents the library portion of the draft ANSI/ISO Standard for the programming language C++, and shows how to use all library classes and functions mandated by that draft standard. An introductory chapter discusses how the standard C library changes to meet the needs of C++. Each of the 38 headers is then covered using the same format: a discussion of how the specific portion of the library is customarily used, excerpts from relevant portions of the draft, the code needed to implement the particular portion and to test the implementation, and exercises and references.
