This page tries to list all the symbols that are available from the [ standard
library ](/w/cpp/standard_library "cpp/standard library") in the namespace
std  . The symbols are written as follows:

  * Function names with ` () ` . 
  * Templates with ` <> ` . 

Symbols from  std  's sub-namespaces (e.g.  chrono  ) are not listed here, but
the namespace names (prepended with the icon ▶) are the links to the
corresponding pages.

[ Macro symbols ](/w/cpp/symbol_index/macro "cpp/symbol index/macro") , [
exposition-only symbols ](/w/cpp/symbol_index/expos "cpp/symbol index/expos")
and [ symbols removed from the standard library
](/w/cpp/symbol_index/zombie_names "cpp/symbol index/zombie names") are listed
in separated pages.
