WebIn C++20 you can also use ranges::for_each such as: ranges::for_each(pairs, print, &pair::second); With an optional 3rd argument for projection, which can be pretty neat. Another noticeable difference with range-for loops is composability; std::for_each returns its operating function, and ranges::for_each returns that paired with its iterator.
