EDIT: Note that this won''t work accurately for binary files.
Dumping it into a string is a waste of time and memory; std::distance() will tell you how far apart the iterators are without recording what''s in the file.
And using istream_iterators is wrong, as they''ll gobble up whitespace. istreambuf_iterators will count everything.
