Martin</A> (milo@cs.wisc.edu)</H4><hr><br><H1 ALIGN=CENTER>Program 4</H1><H3 ALIGN=CENTER>Due Monday, October 21, 1996</H3> <hr><br><b>Objective</B>: Give the student practice doing file inputand output.<p><H3>Program Description</H3>You have been hired as a golf pro at the Big Shank country club.Big Shank actually consists of 5 different 9-hole golf courses, each ofwhich has a separate "par" score. <p>(Notes for people unfamiliar with golf: the object of golf is toobtain as low a score as possible. Your score for each hole is thetotal number of shots it takes to get the golf ball in the hole. Yourscore for the entire round is the sum of your scores for each holes."Par" for a hole is generally the score that a good golfer wouldreceive on that hole, and par for the entire course is the sum of thepars for each individual hole. Golfers try to get a score lower thanpar for the course. For example, each hole in a 9 hole course wouldhave a par score. If par for each hole was 4, then par for the entirecourse would be 36. If a golfer scored 3 on each hole on that course,the golfer would have a score of 27, which is very good, since it isless than, or "under" par. In fact, since 27 - 36 = -9, we say thegolfer is 9 under par. If, on the other hand, a golfer scored 5 oneach hole, the golfer would have a score of 45, and would be 9 over par, whichis not as good. Note that 45 - 36 = 9.)<p>You have been assigned to work at a golf tournament being held at Big Shank. A number of players are each playingone round on each course. Thus, each player will have a different score for each of the 5 courses. In addition,each of the five 9-hole courses at Big Shank has a <i> different </I>par score. All of this data will be stored into an input file.The file will have the following form:<p><PRE> 36 35 36 33 32 124 37 33 35 37 35 2353 37 35 34 32 33 3457 40 31 32 35 28 532 32 35 34 34 30 -1</PRE>The first line lists the par score for each of the 5 courses.Thus, par for the first course is 36, par for the second is 35,and so on.<p>The next 4 lines list the scores for eachindividual golfer on each course. The first part of each of these lines is the "golfer id" number, which you may assumefits into an int. You may also assumethat each ID number is unique. The remaining 5 numbers hold that golfer'sscore for each of the 5 courses. Thus, the first golfer hasan ID of 4343, and has scores of 37, 33, 35, 37, and 35.<p>Finally, a -1 is included in the file, which means that the listing of scores is now complete. When you read in a-1 instead of a positive ID, you can assume all the players havebeen listed. (If there is any input data after the -1, you can ignore it).<P>NOTE: The data in the actual input files will be different thanthe data given above. Thus, you may NOT assume anything aboutthe number of golfers, the par scores for the 5 rounds, and so on. <P> Also, the input file may have a different spacing and line breaksthan the one listed above. For example, the above datacould be present in the input file in the following form:<PRE> 36 35 36 33 32 124 37 33 35 37 35 2353 37 35 34 32 33 3457 40 31 32 35 28 532 32 35 34 34 30 -1</PRE>Note that the data is the same, the only difference is thatthe spacing and line breaks have changed.<P>Your job is to:<LI> Determine the score for each golfer - that is, thegolfer's score relative to the par score. Scores over par should be output with positive numbers, scores below parshould be output with negative numbers, and an "even par" scoreshould be output as 0.<LI> Determine the average score for each course, and the average par score for all golfers.<LI> Determine who won the tournament and what the winningscore was. The winner of the tournament is that personwith the lowest overall score relative to par. You may assumethat there is a unique lowest score - that is, that therewill not be multiple winners with the same lowest score. <LI> Print all of this information neatly to an output file. <BR><BR>Here is how your output file should appear for the sample datagiven above:<p><BR><PRE> Player ID Round 1 Round 2 Round 3 Round 4 Round 5 Final Par Par 36 35 36 33 32 - 124 37 33 35 37 35 5 2353 37 35 34 32 33 -1 3457 40 31 32 35 28 -6 532 32 35 34 34 30 -7 Average 36.50 33.50 33.75 34.50 31.50 -2.25The winner is player #532 with a score of 7 under par.</PRE><BR><BR>The second line, which begins with Par, lists the par scorefor each of the 5 rounds. <P>The following4 lines list data for each individual golfer. First,the golfer's ID is displayed. Next, the golfer's scoreson each of the courses is displayed. Finally, the golfer's overall "par"score is displayed, in the Final Par column.<P>For example, the golfer with the ID 124 scored 37, 33, 35, 37, and35, on rounds 1-5 respectively. Thus, these scores are listed in the 5 "Round" columns. The sum of these scores (177) is 5 more thanthe sum of the par scores for the 5 courses (172). Thus, a 5 is displayedfor golfer 124 in the final par column, where 5 means "5 over par." <p>The next golfer, with an ID of 2353, scored 37, 35, 34, 32, and 33 in the5 rounds. Thus, that golfer's total score (171), is one <i> less </I> than the par score, so a -1 is recorded as the golfer's final par, signaling 1 under par.<P>The scores for the remaining 2 golfers are then printed out, as well as theirfinal scores (6 and 7 under par).<P>The line beginning with Average lists the average total score for each of the 5 courses. For example, since the average of 37, 37, 40, and 32 is 36.5, 36.50 is printed as the averagefor Round 1. The remaining averages for the other 4 rounds areprinted out. Finally, the average tournament par score for allgolfers is printed out. <P>The final line displays the ID of the golfer who wonas well as that golfer's score relative to par. <P>Note that to receive full credit on this assignment, you must formatyour output file in <i> exactly </i> the same way as the sample above.For example, each column should be 10 characters wide, and the averagesshould be displayed with 2 trailing decimal points. <p>We have provided a test input file for you to use, whichis called "golfin.txt". You may find it in the r:\public\program4 directory.Please note that I may use a different input filewhen testing your program, but it will have the same nameand will be formatted in the sameway as golfin.txt and the example given above. <I> You should alsobe sure to make up your own input files to use to test your program as well.</I><P>You should name the output file produced by your program"golfout.txt." <P>Your solution should use functions where appropriate, but you may not use globalvariables. You should check to make sure the file was opened correctly.You need not do any error checking when you read in the data from the file <B> except </B> for the following: if one of the inputscores is <I> smaller </i> than the number of holes (9), which is of course impossible, your program should penalize that cheaterby changing the score on that round to 200.<P>Your program should print out the followingstatements to the screen:<P><PRE>Beginning file processing....Done with file processing. Output file written.</PRE><p> <H3>What To Turn In</H3> Once you have your program working, you should use the test fileprovided, "golfin.txt", as your input file. Then, print out a copy ofthe "golfout.txt" file your program produces. <b>Repeat this for yourown test data. (including the printout)</b> Also print out a copy ofthe C++ source code and submit an electronic copy of your source codeand executable as described in the project 1 directions. <p><hr><address>Created by <!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><!WA3><A HREF="http://www.cs.wisc.edu/~stenglei/stenglei.html">Jeremy Stenglein</A>, and <!WA4><!WA4><!WA4><!WA4><!WA4><!WA4><!WA4><!WA4><!WA4><A HREF="http://www.cs.wisc.edu/~dzimm">Dave Zimmerman</A>.</Address></BODY></HTML>⌨️ 快捷键说明
