std::chrono...y::month_day(3) C++ Standard Libary std::chrono...y::month_day(3) NAME std::chrono::month_day::month_day - std::chrono::month_day::month_day Synopsis month_day() = default; (1) (since C++20) constexpr month_day( const std::chrono::month& m, (2) (since C++20) const std::chrono::day& d ) noexcept; Constructs a month_day. 1) Default constructor leaves the stored month and day values uninitial- ized. 2) Constructs a month_day that stores the month m and the day d. Notes A more convenient way to construct a month_day is with operator/, e.g., std::chrono::April/1. Example // Run this code #include <chrono> #include <iostream> int main() { using namespace std::chrono_literals; constexpr auto mo_da = std::chrono::month_day(std::chrono::February, 29d); std::cout << static_cast<unsigned>(mo_da.day()) << '/' << static_cast<unsigned>(mo_da.month()) << '\n'; } Output: 29/2 See also operator/ conventional syntax for Gregorian calendar date creation (C++20) (function) http://cppreference.com 2024.06.10 std::chrono...y::month_day(3)
