Is there anyone can work out this code?
Suppose you have been recently hired by an athletic department to (eventually) develop computer-based
tools to perform biomechanical analyses of athletes (similar to that described in the 2012 Olympics article
you read). However, before developing such biomechanical computer-based tools, the department wants you
to ﬁrst write a computer program to help with soccer team tryouts (as many more athletes are trying out
this year than in prior years). To help deal with the abundance of athletes trying out for the team, the coach
has decided to perform the tryouts in two rounds, with the ﬁrst round being more objective (and thus more
easily performed with the help of a number of assistant coaches and a computer program) than the second
round. In particular, in the ﬁrst round, a number of assistant coaches will time each of the athletes in 10
events. Each athlete must meet a qualifying time in at least eight of those events to make it to the second
round. More details about this round appear in the next section. In the second round, more traditional
tryouts will be performed (including careful examination of each athlete’s performance during drills and a
game). You have been speciﬁcally asked to write a computer program to help the assistant coaches properly
assess each athlete in the ﬁrst, more objective, round to determine if he/she qualiﬁes for the second round.
You do not need to help with the second round of tryouts as this round is more subjective in nature.
One of the assistant coaches will escort each athlete to 10 events (e.g., 100 m run, kicking a soccer ball at a
target, completing a particular passing drill). The events will be presented to each athlete in a random order.
At a given event, the athlete will have three attempts to achieve a time equal or less than the qualifying
time. The qualifying time for each event appears in Table 1. As soon as an athlete achieves the qualifying
time (or better), the athlete will have “passed” that event and he/she will directly move on to the next event
(and not ﬁnish any remaining attempts that may remain). For example, if an athlete achieves the qualifying
time in the second attempt, he/she will not complete the third attempt. If the athlete’s time is larger than
the qualifying time on all three attempts, the athlete will have “failed” the event. The athlete is required to
pass 8/10 events to qualify for the second round of tryouts. The athlete will stop competing in the events as
soon as his/her qualiﬁcation status is known. For example, if an athlete passes the ﬁrst eight events, he/she
will qualify and will make no attempts on the last two events. Similarly, as soon as an athlete fails three
events, he/she will not qualify and will make no attempts on any of the remaining events
Table 1: Qualifying Times for the 10 Events
Event Qualifying time Event Qualifying time
Event 1 5.4 s Event 6 3.4 s
Event 2 7.2 s Event 7 26.0 s
Event 3 15.0 s Event 8 35.0 s
Event 4 25.0 s Event 9 42.0 s
Event 5 60.0 s Event 10 62.0 s
Your task is to write an interactive C program to guide an assistant coach through the ﬁrst-round tryout
procedure of a single athlete so as to follow the rules indicated above. The coach will start this program (e.g.,
by running the program remotely through his/her tablet) as soon as the athlete begins his/her tryout. The
program should indicate to the coach the ﬁrst event for which the athlete will be timed and the associated
minimum qualifying time. The program should also request that the user (the assistant coach) enter the
time (in seconds) of the ﬁrst attempt of this event. The coach will then time the athlete’s ﬁrst attempt
at the indicated event using a traditional stop watch (not using your program) and will enter the time
achieved using the keyboard. If the athlete does not make the qualifying time on this ﬁrst attempt, the
program should request that the user enter the time (in seconds) of the second attempt. If the qualifying
time has still not been met, the program should request that the user enter the time (in seconds) of the third attempt. Once the event is completed, the program should indicate whether the athlete “passed” or “failed”
the event and specify the next event. This process should repeat until the athlete’s qualiﬁcation status is
known (e.g., by passing eight events or failing three events). The program should then specify whether the
athlete qualiﬁes for the second round of tryouts and provide a summary of the number events passed and
the number of events failed.
You have a lot of ﬂexibility in how you will exactly implement the this C program, but the following
provides some additional general requirements:
• You must implement your program in the ﬁle named hw1.c within your hw1 folder in your homework
directory. Please note that this is an individual assignment and you are correspondingly not allowed
to discuss your program with anyone but the instructor and the TA’s.
• The program must be “interactive” in the sense that the program will guide the user by displaying
instructions/results to the screen what event/attempt the user should time next and by waiting for the
user to enter the corresponding time. It should be obvious to user what they should do when running
• Each time the program is run, the order in which the events are presented to the user must be diﬀerent
(so you will need to be able to randomly generate a permutation of the event order). Please note that
generating such a random permutation is one of the more challenging aspects of this assignment, so
it is strongly recommended that you get your program working with a ﬁxed order (e.g., “Event 1,”
“Event 2,” . . . ) before modifying your program to enable the events to be presented in a random order.
If you do not generate a random permutation of events, you can still receive up to 90/100 points for
the assignment (see grading guidelines).
• The program must not request that the athlete complete any unnecessary attempts of any event. For
example, if the athlete achieves the minimum qualifying time (or better) on an event, the next event
should immediately be presented to the user rather than requesting that the user enter the times
associated with additional attempts. As another example, once it is known that an athlete will qualify
or will not qualify, the program should not request that any times be entered for additional events.
• You must avoid repeating a large amount of code (eﬀectively meaning that you will most likely need
to include loops, arrays, and/or functions). For example, please do not explicitly write out all the code
for each event separately – use some type of loop.
• In addition to having a standard documentation block and providing comments throughout your program, you must provide high-level pseudocode at the level of detail that someone with suﬃcient C
knowledge would be able to implement your program.

Now the real question is why you think you deserve special consideration from the universe by getting someone else to do your homework, whilst your classmates do it for themselves (and learn something in the process).

So you can't play the "nobody to help me" card here.
Go and pester them for help and advice - they're being paid to support you.

Is there anyone who could be bothered to even read the assignment dump!?

Yes. His instructor when he Googles the forums to discover which of his students are attempting to commit plagarism. We've seen that happen here before.
