No, there's no guarantee that in every context \n is translated portably.
The same is true of std::endl. std::endl is simply defined as
<< '\n' << std::flush; nothing more, nothing less. In all cases where endl gives you a "properly translated" newline, so does\n.Ahhh, I see. Looks like the magic happens somewhere further down in iostream.
It's controlled by whether the stream's opened in text mode or binary mode. On Unix, they're the same, but on Windows, text mode has line ending conversion.
