This Clause describes the function signatures that are called
|
||
implicitly, and the types of objects generated implicitly, during the execution
|
||
of some C++ programs[.](#1.sentence-1)
|
||
|
||
It also describes the headers that declare these function
|
||
signatures and define any related types[.](#1.sentence-2)

The following subclauses describe
|

common type definitions used throughout the library,
|

characteristics of the predefined types,
|
||
functions supporting start and termination of a C++ program,
|
||
support for dynamic memory management,
|
||
support for dynamic type identification,
|
||
support for contract-violation handling,
|
||
support for exception processing, support for initializer lists,
|
||
and other runtime support,
|
