Programming Project 4

Golf Statistics Keeper

Out: Sunday, December 3, 2006
Due: Wednesday, December 13, 2005 before 11:59 p.m. 




 The Objective 

This project is designed to give you practice working with arrays
and functions. It will also give you practice passing arrays to 
functions.




 The Task 


You job is to write a program that will read in the golf scores 
of several players in a golf game.  You will then display some
statistics about the scores.  You will generate an average score
and list those players who scored below the average (a good thing!) 
You will also provide the functionality to show the winning score.  
The player with the lowest score is the winner.




Below is the main() function you must use in your program:


int main()
{
   int scoreList [MAX_PLAYERS]; /* Array to store golf scores */
   int numberOfPlayers = 0;     /* Total number of scores entered */
   float averageScore = 0.0;    /* Average golf score */
   int winningScore = 0;        /* The lowest score */

   printf("\nWelcome to CMSC104's Golf Statistics Program!\n\n");

   /* Fill array with golf scores */
   numberOfPlayers = FillGolfScoreList (scoreList);

   /* Print the golf scores */
   PrintGolfScoreList (scoreList, numberOfPlayers);

   /* Find and print the winning (lowest) score */
   winningScore = FindWinner (scoreList, numberOfPlayers);
   printf("The winning score was %d.\n\n", winningScore);

   /* Calculate and print the average golf score */
   averageScore = CalculateAverageScore (scoreList, numberOfPlayers);
   printf("The average score was: %.3f.\n\n", averageScore);

   /* Find and print the players who had scores below the average */
   ProcessBelowAverage (scoreList, numberOfPlayers, averageScore);

   return 0;

}




You MUST use the main() function exactly as it is given.  However,
you need to add the following code before main:



You must also add the definitions of the functions after main().  You may 
add additional functions if you wish.



 Input to the Program 

A data file containing the items for you to use as input to your program will 
be provided.  The items are all greater than 0.  The last value in
the file will be 0.  This is the sentinel value that signals the program 
to stop reading items.


To use the data file as input to your program, you will use Linux redirection.
When you run your program, use the following command:

       a.out < scores.dat




You will need to copy the file scores.dat into your directory.  
To do this, go to the directory where you would like to store 
scores.dat.  Then, use the following command to copy 
scores.dat into the directory:


    cp /afs/umbc.edu/users/d/b/dblock/pub/CS104/Proj4/scores.dat .




Notice that the space and period at the end of the command are part of
the command. 



Here is a example of what the input data file could look like:


76
80
73
74
89
0





You will also find   proj4.c  in the directory with
scores.dat.  You can copy it to your own directory 
following the above directions.



Sample Output


linux2[3]% gcc -ansi -Wall proj4.c
linux2[4]% cat scores.dat 
79
88
94
92
83
82
0

linux2[5]% a.out < scores.dat 

Welcome to CMSC104's Golf Statistics Program!

The following scores were entered:

Player  1: 79
Player  2: 88
Player  3: 94
Player  4: 92
Player  5: 83
Player  6: 82

The winning score was 79.

The average score was: 86.333.

The following players received a score below the average:

 Player #       Score
----------    ----------
    1             79
    5             83
    6             82


linux2[6]% 



Your output does not have to match the sample exactly, with 
a few exceptions:

    


Submitting the Program 




Here is a sample submission command.  Note that the project name 
starts with uppercase 'P'.


submit cs104_0101/0501 Proj4 proj4.c


To verify that your project was submitted, you can execute the
following command at the Unix prompt.  It will show the file that
you submitted in a format similar to the Unix 'ls' command.


submitls cs104_0101/0501 Proj4
