 And the error message is...?  We're not telepathic.

 Then you're no longer using the C++ library.

 This works for everybody else.
 
 The I/O headers with .h were never part of any language standard, so their
 contents vary from one compiler to another.  We provide them just to help
 in moving old C++ code to correct C++ code.  You may be assuming that a
 .h file provides more than it does.
 
 As a start, try including <foo> instead of <foo.h>, and placing a 'using'
 statement after the header.
