APPENDIX I: STANDARD LIBRARY
The C++ Standards Committee Working Group published the International Standard ISO/IEC 14882:1998 in 1998. A revised International Standard ISO/IEC 14882:2003 was published in 2003. Modern compilers support standard library as specified in these standards.
The C++ Standard Library is a collection of classes and functions, which are written in the core language and part of the C++ ISO Standard itself. The C++ Standard Library provides several generic containers, functions to utilize and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and everyday functions for tasks such as finding the square root of a number.
