UMBC CMSC 104 Spring 2001 | CSEE | 104 | current 104 |
Due Date: Midnight, Thursday May 17
Note: No late projects will be accepted.
Point Value:
This assignment is worth 50 points.
Objectives:
This assignment is very similar to Project 6, "Exam Statistics." But this time, you will be reading the exam scores into an array and then producing statistics, rather than processing the exam scores one at a time. You will also be dividing your program into functions. The code for the main function will be supplied (see below). You will need to write the code for the remaining six functions and their prototypes.
Assignment:
Background
Congratulations! You are the new Teaching Assistant for CMSC 104, Section 0106! As part of your job, you are to write a program to analyze class exam scores. Your program should compute
Save your program in a file called proj8.c.
A data file containing the scores for you to use as input to your program will
be provided. (NOTE: These are NOT the real scores from your exams!) The score
s are between 0 and 100, inclusive, and are in random order. The last value in
the file is
-1. This is the sentinel value that signals the program to stop
reading scores.
To use the data file as input to your program, you will use UNIX redirection.
By using redirection, you can tell UNIX to read data from a file rather
than from the keyboard. The scanf
statement that you use in
your program will look exactly the same as it would if you were getting
your input from the keyboard. But since you will be getting the values
from a file instead of from a user typing at the keyboard, you will not
need to prompt the user.
When you run your program, use the following command:
You will need to copy the file proj8.dat into your directory. To do this, go to the directory where you would like to store proj8.dat. Then, use the following command to copy proj8.dat into the directory:
Sample Program Run
Here is an example of what an input data file might look like:
Your program's output should follow this EXACT format.
Main Function
Here is the main function EXACTLY as it should appear in your program. Do NOT alter it IN ANY WAY. (You can simply "cut and paste" the function from this page into your text editor.) Note that you will have to add the following code before the main function:
Coding Standards:
Note that you MUST adhere to the coding standards and indentation style given on the Projects home page. So read them carefully and immediately!
Project Submission:
Submit your project by e-mailing your source code (proj8.c) to Evelyn (cwang3@cs.umbc.edu) as an attachment. Make the Subject of the e-mail Project 8 so that Evelyn knows what it is. Do NOT send your executable file (a.out) or the input data file (proj8.dat).
