| | | | | 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. | |

| | | | | If you want a function that returns multiple values, you'd use a reference and assign the outputs to that. But using a reference has a few drawbacks - it is not obvious in the caller, requires default construction etc. This post will explain why you sometimes need output parameters and how to fix their problems. | |

| | | Criticizing software is easy, yet the C++ and C standard libraries have withstood the test of time admirably. Nevertheless, they are not perfect. Especially the , , and headers. The first two alone bring in over 20,000 lines of code, slowing the compilation of every translation unit by over 100 milliseconds. Most of that code seems dated, slow, and error-prone, with interfaces that are very hard to distinguish. This is not a new problem, and I don't have an exhaustive list of all the issues with STL and ... | ||
