1 This International Standard specifies requirements for implementations of the C++ programming language.
The first such requirement is that they implement the language, and so this International Standard also
defines C++. Other requirements and relaxations of the first requirement appear at various places within
this International Standard.
2 C++ is a general purpose programming language based on the C programming language as described in
ISO/IEC 9899:1999 Programming languages — C (hereinafter referred to as the C standard). In addition to
the facilities provided by C, C++ provides additional data types, classes, templates, exceptions, namespaces,
operator overloading, function name overloading, references, free store management operators, and additional
library facilities.
