Version 2 of the C++ Extensions for Library Fundamentals, ISO/IEC TS 19568:2017, defines the following new components for the C++ standard library, in addition to those defined inversion 1:
Contents |

a class representing a non-owning pointer (class template) |
std::array
creationDefined in header <experimental/array> | |
(library fundamentals TS v2) | creates astd::array object whose size and optionally element type are deduced from the arguments (function template)[edit] |
ostream_joiner
Defined in header <experimental/iterator> | |
an output iterator that writes successive elements into an output stream, separating adjacent elements with a delimiter (class template) |
Aper-thread engine of typestd::default_random_engine, initialized to an unpredictable state, is maintained for each thread and used by the functions below.
