[SOLVED] Small program 4 cop3223c introduction to programming with c

This assignment contains a set of problems that are to be completed in one C file. You have
learned about creating user-defined functions and why they are so beneficial to us programmers.
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 smallprogram4_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 smallprogram4_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 4 Page 1
Eustis all because it worked on your machine. The Eustis environment gives the final say. Plan
accordingly to test on Eustis!!
Displaying Statements! Read Carefully!
Dr. Steinberg and his TAs have noticed that students are not using the escape sequence newline
for the last display statement of past small programs. Please make sure to use the newline
escape character for all statements. The only time you will not use the newline escape character
is when user input is collected. Pay close attention to the screenshots.
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. New Info: 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: After you run the script, 5 new text files are going to be generated.
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.
These files are the solution output for each test case. 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 sp4test.py

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 4
Missing a comment header will result in point deductions!

Problem 1
Write a user-defined function definition called perfectSquare that prints a nice hollow square
made out of * characters. The function has no parameters and does not return any values. Inside

the function definition, you will prompt the user for a number that will be used in generating the
square. If the user inputs an invalid number (0 or negative), then an error message should
display informing the user and to try again. See figure 3 for a sample output of the problem.

Problem 2
Write a user defined function definition called elevator that simulates a menu of an elevator
with options the user can select. The function takes no arguments and does not return anything.
The user defined function will ask the user which floor they would like to go to. The user will
select one of the twelve options and the program will display the floor selected. See figure 4
for the message that is displayed for each respective floor number. If the user selects any valid

option 1-12, the program will ask the user to enter another option. If the user selects option 5,
the program will not loop again and display the message “Elevator door is now open. Please exit
now.” If the user selects an invalid option, the message “That is not a valid option.” is displayed.
Figure 5 shows a sample run on the terminal.

Problem 3
Write a user-defined function definition called pyramid that prints the following following pattern.
The function has no parameters and does not return any values. Inside the function definition,

you will prompt the user for a number that will be used in generating the pattern of ‘-’. If the user
inputs an invalid number (0 or negative), then an error message should display informing the
user and to try again. See figure 6 for a sample output of the problem.

Problem 4
You have been asked by the legendary Ms. Valerie Frizzle to calculate the average of a recent
test from a magic school bus field trip in space. Write a user defined function called classAvg.
The function has one parameter that represents the number of the students in the class. That
value is collected in the main function (you also have to assume that an invalid number 0 or a
negative number could be entered). If an invalid number is entered, then the user should be
asked to enter another value. Once the proper value for the number of students is entered, the
function is then going to prompt the user to enter the test score of each student. The scores can
range from 0 ≤ score ≤ 100 (there can even be decimal values). The function must also handle
if the user enters an invalid score that is not in the provided range. If the user enters an invalid
score, the program will the user again to input the proper value. Once all scores are entered, the
average is computed and sent back to the main function to be displayed. The value of average
is of type double. The resulting average is displayed as a percentage up to four decimal places.
The following figure shows a sample run with class size of 4. For this problem, you cannot use
arrays (we have not covered them yet)! If arrays are used, then No Credit will be given for this
problem.
