std::chrono::month_day_last
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_day_last & mdl ) ;
(since C++20)

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

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

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

Return value

os
