#  inefficient.py:
 #  Author:  James Tam
 #  Version: January 25, 2008
 
 #  A program that conerts a numeric gpa to a letter grade. The current version
 #  of the program assumes that only integer gpa values will be used and
 #  will truncate any real number values entered.
   
 #  Note: A program written to illustrate why you should use if-elif-else
 #  statements if you have exclusive multiple conditions.  While this program
 #  does produce the same output as efficient.py it does so in far less
 #  efficient fashion because now every conditional if will be checked even
 #  though only one of them will be true.
