[SOLVED] Small program 7 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 smallprogram7_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 smallprogram7_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!
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
operating system. Remember, you cannot dispute grades if your code didn’t work properly on
Small Program 7 Page 1
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!
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: If you have these files, you are ready to run the script. Use the following
Figure 1: Your setup for testing on Eustis. 5 sample txt files (provided for you in Webcourses),
your C program, and the python test script.
command to test your code with Dr. Steinberg’s provided solution sample.
python3 sp7test.py
After you run the script, 5 new text files are going to be generated. These files are the solution
output for each test case. 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 7
Missing a comment header will result in point deductions!

Problem 1
Write a user defined function called deblank that takes a string phrase output and a string
phrase input argument and copies the input argument with all blanks removed and stores the
result in the output string. Blanks are the white spaces in a string. For this problem, declare the
strings of size 20 and ask the user to input one to store. Display the output result in the main
function. The following figure shows a sample output in the terminal.
Figure 3: Sample output for problem 1. Make sure it matches for the python script.
Problem 2
Write a user defined function called pluralize that takes a noun as a string input and will
pluralize the word. The result should be displayed in the main function. Note the following rules
about noun plurals:
a) If noun ends in “y”, remove the “y” and add “ies”.
b) If noun ends in “s”, “ch”, or “sh”, add “es”.
c) In all other cases, just add “s”.
For this problem, declare a string of size 20 and ask the user to input one. The following figure
shows a sample output in the terminal.

Problem 3
Write a user defined function called fact that takes a one word string as input and determines
how many letters, digits, and punctuation characters it contains. The results should be displayed
in the user defined function. For this problem, declare a string of size 20 and ask the user to
input one. The following figure shows a sample output in the terminal.
Figure 5: Sample output for problem 3. Make sure it matches for the python script.
Problem 4
Write a user-defined function called substring that takes two strings as arguments. If the
second string (in the argument) is contained, the memory address at which the contained string
begins is returned. For example, substring(“turkey”, “key”) would return the memory address
of the k in “turkey”. Otherwise return a NULL pointer. In the main function, ask the user
for the two strings. Once the strings are entered, call the user defined function. Once the
function has returned a resulting value, display message of the result. For example substring(“turkey”, “key”) would cause the message “Substring key exists!” to
be displayed. The function call substring(“store”, “too”) would cause the message
”Substring too doesn’t exist!” to be displayed. Note: The strings are only single
words. Do not worry about sentences! You cannot use the built in strstr() function to
solve this problem or any built in memory function! Using any of these functions will
result in a score of 0 for this question. You can assume that the first string argument is
always bigger than the second string argument. For this problem, declare a string of size
20 and ask the user to input one. The following figure shows a sample output in the terminal.
Super Big Hint: Your function is going to return an address type value, think about how your
user defined function header would look. You should have notice something during lectures.

sure it matches for the python script.
