Actually, that reason isn't accurate.  The '\n' is an expression of 
type char, and all output streams can print a char object with operator 
<<, even if the stream's character type isn't char.  (The stream will 
secretly call the widen member function.)  Unlike using a manipulator, 
printing a character this way also activates all the formatting 
considerations.
