Scanning whitespace

-----------------------------------

Anybody know how to scan whitespace?

I need to be able to scan something like

Dear, world.

 I hate you so very, very much.

 Regards, Rosie O'Donnell

With the \n's and \t's in there.  Thanks bunch.

what do you mean by "scan"? If you mean parse a string, then yes it's super easy. If you mean remove whitespace, then that too is easy.

so you want to read in input including whitespace? The easiest way is just to read in characters and add them to a string. There are other ways involving reading entire lines and stuff, but those are slightly more complex.
