Assignment 7b: 19 points
Write a Program: Competition Score (continued)
Use Assignment 7a as your starting point. The description of this assignment is
ather long, but you have already written most of the code – you just need to
modularize it appropriately and account for multiple athletes.
Your goal is to create a program that will determine average scores for a group of
up to 10 athletes in a competition. There are 10 judges who each award scores
etween 0 and 10. The lowest and highest scores are thrown out, and each
athlete’s score is the average of the eight remaining scores.
I provided 2 scorecard files for you to use. The scorecards have two lines for each
athlete. The first line has the name of the athlete and the second line has 10
space-separated scores between 0 and 10. The number of athletes in the 2
scorecards is different.
Your program should get the scorecard file name from the user, read the
scorecard, and create the same output as in assignment 7a for each athlete.
Your program should have the following:
ï‚· Include 4 comment lines at the top: description of the program, author,
section, and date. (1 point)
ï‚· Global named constants for the maximum number of athletes and the
number or scores per athlete. (.5 points)
ï‚· Local named constants as appropriate. Remember that each function is
esponsible for its own functionality. (1 point)
ï‚· An a
ay to hold the names of the athletes, an a
ay to hold e
or messages
if an e
or is encountered while reading data for individual athletes, and a
two-dimensional a
ay to hold the scores from all judges for all athletes.
(1.5 points)
 A function (Function 1) that reads the athletes’ names and scores from the
scorecard.
o The function should store the names in the name a
ay (1 point)
o The function should store the scores in the two- dimensional score
a
ay. Do not forget to ignore (hint) the end line character from the
stream after you read each line with the scores so you can read the
next athlete’s name co
ectly. (2 points)
o For each athlete, if a score outside the valid range is encountered the
function should store an e
or message in the e
or a
ay and
proceed to reading the next athlete’s data. Otherwise, an empty
string should be stored in the e
or a
ay. (1 point)
o The function should return the number of athletes it successfully
ead from the scorecard (including the ones that will be disqualified
ecause of invalid scores). This number can be 10 if the scorecard has
at least 10 athletes, or less if the end of file is encountered sooner.
You should not attempt to read the data for more than 10 athletes.
Hint1: An input stream object will evaluate to false after any read
operation that encounters an EOF. Hint2: Function getline() returns
its first parameter (the input stream from which it reads). (2 points)
o In this assignment (unlike 7a) you don’t need to handle the scenario
when there’s an insufficient number of scores for an athlete. If, while
eading the scores, the stream evaluates to false just assume that
eading the cu
ent athlete’s data is unsuccessful and return the
number of athletes you have already read by that point. Hint: That
number will be your loop counter value. (1 point)
ï‚· A function (Function 2) that processes the scores and computes the
average for one athlete.
o This function finds the highest and the lowest scores to throw away,
computes the average of the eight remaining scores, and returns it.
(2 points)
o It also displays the 10 scores to the console and reports the two
scores that were dropped. (1 point)
ï‚· The main function should:
o Ask the user to enter the filename of the scorecard. (1 point)
o Call Function 1 to read the scorecard and get the number of athletes
whose data was successfully read. (1 point)
o For each such athlete: (3 points)
 display the athlete’s name
 check if there was an e
or validating the scores and display a
message that the athlete is disqualified
 if the e
or message is an empty string call Function 2 to
compute the average score
 display the average score on the console
Notes:
 When you run your program, you should test it with both scorecards. You
should also test your program when the scorecard file is not present. This
is a total of 3 runs. Insufficient console output is a 1-point deduction.
 Pay attention to where you create and how you initialize your variables.
Unsafe code is a 1-point deduction.
 Remember to create named constants for what’s appropriate. Use the
standard convention for constant names. Imprope
insufficient use of
named constants is an up to 1-point deduction.
 Comment your code. Uncommented code is a 1-point deduction.
