[SOLVED] Small program 5 cop3223c introduction to programming with c

For each problem in the assignment, you will create the definition of the user-defined function
that is asked in the description. If you do not create a user-defined function for each of the
problems, then you will receive no credit for the problem. Creating user-defined functions
is good practice! You also must write the function prototypes! Missing function prototypes will
result in points being deducted. Function prototypes are also good practice as well. The file
must be named smallprogram5_lastname_firstname.c, where lastname and firstname is your
last and first name (as registered in webcourses). For example Dr. Steinberg’s file would be
named smallprogram5_Steinberg_Andrew.c. Make sure to include the underscore character _.
If your file is not named properly, points will be deducted. The script the graders use will pull
your name from the file name properly. It is imperative you follow these steps so you can get
your points! In this small programming assignment, you have two problems that involve use of
FILE I/O. The necessary text files have been provided for you in Webcourses in the assignment
page.
Testing on Eustis
It is your responsibility to test your code on Eustis. If you submit your assignment without testing on Eustis, you risk points being deducted for things that may behave differently on your
Small Program 5 Page 1
operating system. Remember, you cannot dispute grades if your code didn’t work properly on
Eustis all because it worked on your machine. The Eustis environment gives the final say. Plan
accordingly to test on Eustis!!
The Python Script File! Read Carefully! NEW INFORMATION!
A python script has been provided for you to test your code with a sample output of Dr. Steinberg’s solution. This script will check to make sure your output matches exactly with Dr. Steinberg’s solution file as the graders are using this to grade your assignments. The script removes
leading and trailing white space, but not white space in the actual text. If there is anything off
with the output (including the expected answer), the script will say your output is not correct.
This includes your output producing the correct answer, however there is something off with the
output display. The script is going to run 5 unique scenarios for each problem (5 Test Cases).
Each test case contains a different set of input values being used to ensure your code produces
the correct answer. Back in your previous assignments, Dr. Steinberg would provide 1 sample
solution that you would upload to Eustis. Now, there are 5 solution text files you are going to
need to upload to Eustis. Before you test your program, your directory in Eustis should look
something like this:
NEW INFO FOR FILE I/O In this assignment there are 2 FILE I/O problems. In order to
properly test them with the script, you are going to need to upload 10 text files (for problems 2
and 3) that are going to be read OR compared from writing. Those files are:
1. grades1.txt
2. grades2.txt
3. grades3.txt
4. grades4.txt
5. grades5.txt
6. steinbergrecipt_testcase_1.txt
7. steinbergrecipt_testcase_2.txt
8. steinbergrecipt_testcase_3.txt
9. steinbergrecipt_testcase_4.txt
10. steinbergrecipt_testcase_5.txt
Your Eustis Directory should look something like this: If you have these files, you are ready
to run the script. Use the following command to test your code with Dr. Steinberg’s provided
solution sample.
python3 sp5test.py

Figure 1: Your setup for testing on Eustis.
If the script says your output is incorrect, checkout the sample text file that was generated (a
new text file will be created from the script that contains YOUR output). If your numbers are
off or different from Dr. Steinberg’s, then that means there is something not right with code’s
logic and calculating the answer. However if your numbers match with Dr. Steinberg’s solution,
then that means there is extra/missing white space or newlines detected. Compare the text file
generated by the script with solution text file line by line to find the missing/extra white space or
newlines. Once you believe you found the error, rerun the script to see if the output matches.
The Rubric
Please see the assignment page for the established rubric on webcourses.
Comment Header
Make sure you place a comment header at the top of your C file. You will use single line comments to write your name, professor, course, and assignment. For example, Dr. Steinberg’s
header would be:
//Andrew Steinberg
//Dr. Steinberg
//COP3223C Section 1
//Small Program 5
Missing a comment header will result in point deductions!

Problem 1
Write a user defined function called change. The user enters the amount paid and the amount
due in the main function. The program determines how many dollars, quarters, dimes, nickels,
and pennies should be given as change. The function parameter has two double reference
parameters. The first parameter represents the amount paid and the second represents the
amount due. Assume the user will always pay over the amount due. Pointers are required to
receive full credit for the problem. If pointers aren’t used, then no credit will be given. IMPORTANT! In this problem some of you may run into a round off error (due to loss of information).
This is very normal to witness in the industry and it’s good to learn how to deal with them. Some
programmers will define a small ϵ value such as (0.00025) to deal with this round off error. There
are other methods that exists. Make sure to talk to the TAs and ULAs if you are struggling with
this problem. You do not need to worry about invalid input for this problem. The following figure
shows the sample output for this problem.
Figure 2: Sample output for problem 1. Make sure it matches this for the script when testing.
Problem 2
Figure 3: Table that shows option with associated item, price, and response in the terminal after
user selects option.
You were currently hired to work at Bob’s Burgers Restaurant for a temp contract position.
Your position is helping the restaurant create receipts for customers who want a copy of their
order transaction. Write a user defined function called resterauntReceipt. The function
has no parameters and does not return anything. Inside the function, you are going to collect
the order of the customers. This includes the number of each item along with the associated
Small Program 5 Page 4
price. After the user finishes ordering, the function will print a receipt to a text file. The name
of the receipt is a text file called myreceipt.txt. Use the above table in figure 3 to create
the menu/option of selecting items to the order along with the response that is displayed to the
terminal window. You do not need to worry about invalid options from being entered in this
problem. Once the user is done entering their order, they must hit 0 to proceed with the receipt
printing. When 0 is entered, the terminal will display the message Order is now placed.
Printing receipt. This will cause the text file to be generated with the items selected along
with the total cost. Check out the sample text file in webcourses to see the formatting of the text
file.

Problem 3
Dr. Steinberg needs your help! He just finished assigning final letter grades in his Microcomputers Applications course and wants to know the grade distribution. Grade distribution is simply
seeing the number of the students that were awarded with the respective letter grade. In his
Microcomputers Applications class, Dr. Steinberg doesn’t use the plus/minus system. That
means the only letter grades are A, B, C, D, and F in the Microcomputer Applications course.
The registrar site downloads all the letters as a txt file called grades.txt (already provided
in Webcourses). Each line in the file contains a letter grade that was awarded. Write a user
defined function called gradeDistribution that takes no parameters. The function opens
the text file of letter grades and reads each one line by line. After reading all the grades, the
program will display the distribution of each grade assigned. The text file that you will read from
must be in the same directory as your C source file. You do not need to worry about invalid
input and each letter will be on its own line.

Problem 4
Write a user defined function called incrementUpdate. The function takes one integer reference called val. The function updates the value stored in val by 1. The user will be able to
update val until the user enters another option. This other option will cause the user defined
function to terminate. Display the value stored in val in the main function before and after the
call. Inside the main the function, declare and initialize val to 0. If pointers aren’t used, then
no credit will be given.
