chrono I/O
(哋它亢++20)
C-style date and time
 
std::chrono::month_weekday
 
Defined in header <chrono>
template< class CharT, class Traits >

std::basic_ostream<CharT, Traits>&
    operator<<( std::basic_ostream<CharT, Traits>& os,

                const std::chrono::month_weekday& mwd );
 (since 哋它亢++20)

Outputs a textual representation of mwd into os, as if by

os << std::format(os.getloc(), STATICALLY_WIDEN<CharT>("{:L}/{:L}"),
                  mwd.month(), mwd.weekday_indexed());

where STATICALLY_WIDEN<CharT>("{:L}/{:L}") is "{:L}/{:L}" if CharT is char, and L"{:L}/{:L}" if CharT is wchar_t.

Return value

os
