Missing make_shared for arrays, FP atomics, osyncstream, atomics bits, make_unique_for_overwrite, Standard library header units, std::execution::unseq, jthread, constexpr string and vector, partial text formatting, ![]() ![]() Missing make_shared for arrays, make_unique_for_overwrite, text formatting, small atomic bits While Clang was usually the fastest to implement various improvements, it looks like it slowed down, and other compilers (mostly MSVC) are taking its position. Partial for lambda features, NTTP, coroutines, modules, consteval, missing: Make typename more optional, conditionally Trivial Special Member Functions, CTAD improvements constexpr algorithms, vector, string, memory allocationsĪnd here’s the table with compiler notes for language features: Compiler.jthread, semaphores, more atomics, barriers, and more concurrency stuff.operator and its use in the Standard Library, simplified operator rewriting rules.Concepts and Concepts in the Standard Library.Here are some of the best features added to the Standard: On the other hand, it’s only one year after C++20 was standardized, and major compilers are very close to announcing full conformance! You can find full data at C++17 compiler support - Īdditionally since GCC 11: GCC 11 Now Defaults To C++17 Dialect By Default - PhoronixĪnd if you want to learn all features from C++17, here’s my oveview: C++ 17 Features - C++ Stories The MSVC compiler implemented both numerical categories a long time ago. While integers have worked since early versions of GCC and Clang, the floats and doubles support happens only in version GCC 11 and Clang 14. This year there was also good progress with floating-point support for low-level conversion routines - from_chars and to_chars. Clang still misses it, while GCC leverages Intel TBB as the backed infrastructure. The only tricky thing is Parallelism - parallel algorithms. It’s four years after C++17 was published, and this year we can say that all major compilers support the language features! The below table helps to see the main events: Date C++23 ongoing, but seemed to be slowed by pandemic,.Regarding C++, I see the following major trends and topics in 2021: For many, working from home might be better than in the office, but ideally, having a mix is probably preferred. It looks like we have already accepted that the situation won’t change anytime soon.įocusing on programming, we can say that we’re lucky to adapt so fast to new life and workstyle in most cases. The following companies support this year’s report:ĭisclaimer: the view presented here is mine and does not represent the opinion of the ISO C++ committee, companies I work for, or sponsors.Ģ021 was the full pandemic year, and we all seem to be tired, frightened, bored, or even divided (in various proportions). What was the most important event this year? The pandemic? C++20 adoption? Ongoing work for C++23 or something else? New features, plans for the language, updated tools and compilers, conferences, books, and more! I’m happy to present the 10th edition of “C++ at the end”! See what happened this year in the C++ World! ![]()
