Revision as of 15:13, 31 December 2014
C++17 (also called C++1z) is the informal name for the future revision of the C++ ISO/IEC standard. The specification for the C++17 revision is speculated to be finished in 2017.
Expected features
As the specification for C++17 is just beginning, the following list is just a start. Many features will certainly be added in the next years.[1]
- Addition of a default text message for
static_assert - Removal of trigraphs[2]
- Allow
typenamein a template template parameter - New rules for
autodeduction from braced-init-list[3][4] std::uncaught_exceptions, as a replacement ofstd::uncaught_exception[5][6]- Nested namespace definition[7][4]
- Attributes for namespaces and enumerators[8][6]
- UTF-8 character literals[9][6]
- Constant evaluation for all non-type template arguments[10][6]
- Folding expressions[11][6]
- New insertion functions for
std::mapandstd::unordered_map[12][13] - Uniform container access [14][13]
- Definition of "Contiguous Iterators" [15][13]
- Removal of some deprecated types and functions like
std::auto_ptr,std::random_shuffleor old function adaptors[16]Cite error: The<ref>tag has too many names (see the help page).
