But even "avoiding iostream" is stupid. The author presumably really means "avoid operator>> and operator<< for I/O". Even using type-safe printf-like stuff ultimately still sits on top of iostream.
<format> doesn't require iostream.
fair, but it generates a std::string .. if you want to see it, what are you going to do with it? use .c_str() ??
If you want to see it where? If you want a string you've got a string. If you want to write text to something resembling file I/O (e.g. stdout) then std::print and std::println are what you need instead of std::format
Stroustrup's I/O Streams is a weird dead-end C++ technology. Bjarne is probably never going to get over it, but everybody else should forget about it ASAP.
