can't use ofstream argument in header file

hi i have a .h file i dont include anything inside

i want to pass a reference to ofstream

but it shows error

error C2061: syntax error : identifier 'ofstream'

in the cpp file i include fstream and use namespace std

is it possible to solve this problem?

#include <fstream> in the header as well (without that using directive). If you really only need to use std::ostream instead of std::ofstream then you can #include <iosfwd> in the header and #include <ostream> in the source file.
