std::chrono::year::year(3) C++ Standard Libary std::chrono::year::year(3) NAME std::chrono::year::year - std::chrono::year::year Synopsis year() = default; (1) (since C++20) explicit constexpr year( int y ) noexcept; (2) (since C++20) Constructs a year object. 1) Default constructor leaves the year value uninitialized. 2) If y is in the range [-32767, 32767], constructs a year object holding the year value y. Otherwise the value held is unspecified. Example // Run this code #include <chrono> #include <iostream> int main() { using namespace std::chrono; constexpr int leap_years = [] { int count{}; for (int i{year::min()}; i <= int{year::max()}; ++i) if (year{i}.is_leap()) // uses constructor (2) ++count; return count; } (); static_assert(15891 == leap_years); std::cout << "There are " << leap_years << " leap years in the range [" << int(year::min()) << ", " << int(year::max()) << "].\n"; } Output: There are 15891 leap years in the range [-32767, 32767]. http://cppreference.com 2022.07.31 std::chrono::year::year(3)
