Log of Execution for Athletes Program
-------------------------------------
This program reads in a series of judges' scores
for two different athletes and computes an
average score for each.
Enter next athlete information:
judge #1 score? 8.8
judge #2 score? 9.2
judge #3 score? 8.5
judge #4 score? 9.7
judge #5 score? 8.4
Enter next athlete information:
judge #1 score? 9.2
judge #2 score? 8.2
judge #3 score? 8.6
judge #4 score? 8.8
judge #5 score? 8.0
Athlete #1 average score = 8.92
Athlete #2 average score = 8.559999999999999
