// lec 11 exercise 2

//

// Write a C++ class that:

// - is given the name of a file as a constructor argument

// - has a “GetNextWord( )” method that returns the next whitespace or

//   newline-separate word from the file as a copy of a “string”

//   object, or an empty string once you hit EOF.

// - has a destructor that cleans up anything that needs cleaning up
