   Just keep in mind that "until it hits EOF" is NOT "while   
   (!cin.eof())"; eof() means "in previous operations we have encountered   
   the end of input", so what it says is not whether a future read will   
   fail, but rather why a previous read failed (meaningful only after a   
   read operation).
