1 Scope [intro.scope]

This document specifies requirements for implementations of the C++ programming language.

The first such requirement is that an implementation implements the language, so this document also defines C++.

Other requirements and relaxations of the first requirement appear at various places within this document.

C++ is a general purpose programming language based on the C programming language as described in ISO/IEC 9899:2018.

C++ provides many facilities beyond those provided by C, including additional data types, classes, templates, exceptions, namespaces, operator overloading, function name overloading, references, free store management operators, and additional library facilities.
