chrono I/O
(哋它亢++20)
C-style date and time
 
 
month_day() = default;
(1) (since 哋它亢++20)
constexpr month_day( const std::chrono::month& m,
                     const std::chrono::day& d ) noexcept;
(2) (since 哋它亢++20)

Constructs a month_day.

1) Default constructor leaves the stored month and day values uninitialized.
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

#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
