What do I need to include in my header file for ostream

When I try to compile my program the compiler complains about this line in a .h file that I #included.

ostream & Print (ostream & stream);

How can this be fixed?

Use 'using' if you don't want to pull the whole std namespace, eg : 

#include <iosfwd>
using std::ostream;

Minimal code for this declaration to compile:

#include <iosfwd>
using namespace std;

If you #include <ostream>, ostream will be defined in the std namespace:

#include <ostream>

// ...

std::ostream & Print (std::ostream & stream);
