  Description
 
  The ifstream class is an istream derivative specialized for disk file
  input. Its constructors automatically create and attach a filebuf buffer
  object.
 
  The filebuf class documentation describes the get and put areas and
  their associated pointers. Only the get area and the get pointer are
  active for the ifstream class.
