  5. * This program asks the user to enter 10 real numbers, stores them in an array, echoes the    *
  6. * input back to the user, and then reports the largest and the smallest value entered.        *
  7. *                                                                                             *
  8. * Algorithm (high level):                                                                     *
  9. *   1) Read 10 numbers into an array.                                                         *
  10. *   2) Echo the numbers back to the user.                                                     *
  11. *   3) Initialize largest and smallest to the first element.                                  *
  12. *   4) Scan through the rest of the array, updating largest/smallest as needed.               *
  13. *   5) Display the results.                                                                   *
