// 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

#include <iostream>
#include <cstdlib>
#include <unistd.h>
#include "GetWord.h"

  std::cout << "Usage: " << name << " filename" << std::endl;
