Many developers in 2022 were targeting C++23 features, but actual production use was rare outside experimental code.
| Feature | Why it matters | |---------|----------------| | | Replacing #include for faster builds, better encapsulation. Still not universal due to build system support lagging. | | Coroutines | co_await , co_yield , co_return — efficient async code without callback hell. Used in libraries (cppcoro, asio). | | Concepts | Clean template error messages, overload resolution based on constraints. | | Ranges | std::ranges::sort , views, composition: auto result = vec \| std::views::filter(...) \| std::views::transform(...); | | std::span | Safe, non-owning view of contiguous data (replaces (T*, size_t) ). | | std::format | Python-style formatting ( "{} {}", name, age ) – safer and faster than iostream or sprintf . | | std::chrono extensions | Calendar ( year_month_day ) and time zone support. | | constexpr enhancements | constexpr virtual functions, std::vector , std::string in compile-time code. | c++ 2022
Though technically voted in late in the process, this feature revolutionized how we write member functions. It allows explicit object parameters, drastically simplifying the implementation of recursive lambdas and removing the need for const and non- const overloads of the same function. Many developers in 2022 were targeting C++23 features,
In 2022, C++ experienced a significant resurgence, earning the title of after achieving a record-breaking 4.62% growth in popularity . This milestone was driven by the rapid adoption of modern standards like C++17 and C++20, and the finalized development of the next major iteration, C++23. The C++20 Adoption Wave | | Coroutines | co_await , co_yield ,
: Other major C++20 features gaining traction included Ranges for functional-style data processing, Coroutines for asynchronous programming, and std::format for modern text formatting. Progress Toward C++23
