  5. * CALCULATE AVERAGE TEST SCORE
  6. * ____________________________________________________________
  7. * This program calculates the average of five test scores 
  8. * provided by the user and displays the result.
  9. *
  10. * Computation is based on the formula:
  11. * average = (score1 + score2 + score3 + score4 + score5) / 5
  12. * ____________________________________________________________
  13. * INPUT
  14. * score1 : First test score (as a double)
  15. * score2 : Second test score (as a double)
  16. * score3 : Third test score (as a double)
  17. * score4 : Fourth test score (as a double)
  18. * score5 : Fifth test score (as a double)
  19. *
  20. * PROCESSING
  21. * sum    : The sum of the five test scores
  22. *
  23. * OUTPUT
  24. * average : The average of the five test scores
