void println( std::FILE* stream,

void println();

void println( std::FILE* stream );

Format args according to the format string fmt with appended '\n' (which means that each output ends with a new-line), and print the result to a stream.

1) Equivalent to std::println(stdout, fmt, std::forward<Args>(args)...).
2) Equivalent to performing the following operations:

(until C++26)

std::print(stream, std::runtime_format(
