| | | | | The ISO Committee accepted and published the C++17 Standard in December 2017. In this mega-long article, I've built (with your help!) a list of all major features of the new standard. Please have a look and see what we get! Language Features New auto rules for direct-list-initialization static_assert with no message typename in a template template parameter Removing trigraphs Nested namespace definition Attributes for namespaces and enumerators u8 character literals Allow constant evaluation for all non-type template arguments Fold Expressions Unary fold expressions and empty parameter packs Remove Deprecated Use of the register Keyword Remove Deprecated operator++(bool) Removing Deprecated Exception Specifications from C++17 Make exception specifications part of the type system Aggregate initialization of classes with base classes Lambda capture of *this Using attribute namespaces without repetition Dynamic memory allocation for over-aligned data __has_include in preprocessor conditionals Template argument deduction for class templates Non-type template parameters with auto type Guaranteed copy elision New specification for inheriting constructors (DR1941 et al) Direct-list-initialization of enumerations Stricter expression evaluation order constexpr lambda expressions Different begin and end types in range-based for [[fallthrough]] attribute [[nodiscard]] attribute [[maybe_unused]] attribute Ignore unknown attributes Pack expansions in using-declarations Structured Binding Declarations Hexadecimal floating-point literals init-statements for if and switch Inline variables DR: Matching of template template-arguments excludes compatible templates std::uncaught_exceptions() constexpr if-statements SFINAE Tag dispatching if constexpr Library Features Merged: The Library Fundamentals 1 TS (most parts) Removal of some deprecated types and functions, including std::auto_ptr, std::random_shuffle, and old function adaptors Merged: The Parallelism TS, a. | |

| | | | | In C++11, we got a handy way to initialize various containers. Rather than using push_back() or insert() several times, you can leverage a single constructor by taking an initializer list. For example, with a vector of strings, you can write: std::vector vec { "abc", "xyz", "***" }; We can also write expressions like: for (auto x : {1, 2, 3}) cout << x << ", "; The above code samples use std::initializer_list and (some compiler support) to hold the values and pass them around.
