1 General [intro]

Clauses [lex] through [cpp] describe the C++ programming language. That description includes detailed syntactic specifications in a form described in [syntax]. For convenience, Annex [gram] repeats all such syntactic specifications.

Clauses [language.support] through [thread] and Annex [depr] (the library clauses) describe the Standard C++ library. That description includes detailed descriptions of the templates, classes, functions, constants, and macros that constitute the library, in a form described in Clause [library].

Annex [implimits] recommends lower bounds on the capacity of conforming implementations.

Annex [diff] summarizes the evolution of C++ since its first published description, and explains in detail the differences between C++ and C. Certain features of C++ exist solely for compatibility purposes; Annex [depr] describes those features.

Throughout this International Standard, each example is introduced by “[ Example:” and terminated by “ — end example ]”. Each note is introduced by “[ Note:” and terminated by “ — end note ]”. Examples and notes may be nested.
