/*
   This program demonstrates how the functions 'toupper()' and
    'tolower()' are used to change the case of character (char)
    variables.

   NOTE:  To change the case of an entire word (apstring), you
          will need to convert the case of each letter in the
          word; you cannot convert the case of the entire word
          all at once.
