C++ Standard Library

In the C++ programming language, 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. The C++ Standard Library also incorporates 18 headers of the ISO C90 C standard library ending with ".h", but their use is deprecated. No other headers in the C++ Standard Library end in ".h". Features of the C++ Standard Library are declared within the std namespace.

The C++ Standard Library is based upon conventions introduced by the Standard Template Library (STL). Although the C++ Standard Library and the STL share many features, neither is a strict superset of the other. In particular, the C++ Standard Library has also been influenced by the work of Alexander Stepanov and Meng Lee.

The C++ Standard Library underwent ISO standardization as part of the C++ ISO Standardization effort, and is undergoing further work regarding standardization of expanded functionality.

Famous quotes containing the words standard and/or library:

    “There is a certain standard of grace and beauty which consists in a certain relation between our nature, such as it is, weak or strong, and the thing which pleases us. Whatever is formed according to this standard pleases us, be it house, song, discourse, verse, prose, woman, birds, rivers, trees, room, dress, and so on. Whatever is not made according to this standard displeases those who have good taste.”
    —Blaise Pascal (1623–1662)

    “The fear of failure is so great, it is no wonder that the desire to do right by one’s children has led to a whole library of books offering advice on how to raise them.”
    —Bruno Bettelheim (20th century)
