[GD-General] Checking for unnecessary #included files

[Amy P. <Am...@cs...>]

Good morning!

Do you know of any programs or scripts that can be used to check a source
base for unnecessary #includes?  I would like it to pick up on header files
that are included but none of the contents are used.  Also I'd like it to
realise where you have a pointer to an object, and could replace 

#include "ClassA.h" 

with a declaration

class CClassA

Does such software exist, either as freeware or to buy?  

Thanks,

	Amy
