Custom manipulator for class

Question

I\'m trying to write a stream manipulator with arguments. I have class with 3 int\'s CDate(Year, Month, Day). So I need to make manipulator date_format(const char*)

Answer 1

Manipulators with arguments don't work the same as those without arguments! The are just classes with a suitable output operator which instead of outputting a value manipulate the stream's state. To manipulate the stream state you'll probably set up a suitabe value stored with an iword() or a pword() associated with the dtream and used by the output operator.
