-  *strstream classes are declared in <strstream>
-  *stringstream classes are declared in <sstream>
-  If you want to use both classes you must include both headers
-  *strstream classes are deprecated, stop using them and move to *stringstream

As Paolo said, a good book would be the best help here.
