[SOLVED] Small program 3 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 smallprogram3_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 smallprogram3_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 3 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 does not point directly where your mistake(s) are in the code. It will
only produce a success or unsuccessful output message as a whole. If you get an unsuccessful
output my suggestion is to look at the sample solution text file provided to see what is different
from your answer and Dr. Steinberg’s when comparing. If you have extra white space or new
lines or even just missing a space/new line, you will lose points that won’t be changed!
Make sure you place the python script in the same directory as your C file. You can use the ls
command to check to see if the following items are in the directory.
ls
You should these three files in your directory.
1. Your C File.
2. The Python Script File
3. Sample Solution Text File
If you have these three files. You are ready to run the script. Use the following command to test
your code with Dr. Steinberg’s provided solution sample.
python3 sp3test.py
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 3
Missing a comment header will result in point deductions!

The Solution Text File
You are provided a solution file that was created by Dr. Steinberg’s Python Script. Now you may
notice some strange things about the file. In this assignment, you are going to write statements
that involve interacting with the user. Now you are probably wondering from the solution text file
where the interaction is happening? The fact is that the Python script handles the interaction.
The script creates an input stream that feeds it input. That is why you don’t see the input
directly in the text file. For example, the text file on the first line says Enter a key from the
keyboard: Lower!. Here this looks like we should be typing input, however the python
script has already fed it input. That is why you don’t see the values except for the results. In
each problem, a screenshot of the C file being executed manually without the Python script
shows how it looks on a normal run. Carefully look at the output in the pictures provided. Note:
The arrow symbolizes that the text wrapped onto the next line of the pdf file. In the text file itself
it is actually one whole line.

Enter a key from the keyboard: Lower!

Problem 1
Write the definition of a user-defined function called letters. The function will determine if
a character value is a letter in the English Alphabet. The function has no parameters. Inside,
the definition, you will prompt the user to input a character. If the letter is lowercase, then the
message “Lower!” is displayed to the terminal. If the letter is uppercase, then the message
“Upper!” is displayed to the terminal. If the character value is not part of the alphabet, then
the message “Not a Letter!” is displayed to the terminal. Hint, think about what happens
when characters are evaluated. The following figure shows a sample output scenario when the
letter is lowercase. Make sure your output matches to receive potential credit. Do not worry if
the user enters multiple characters at once. We have not learned strings yet!
Figure 1: Sample output when the key entered from the keyboard is a lowercase letter from the
English Alphabet.
Problem 2
You are a super being in need of a super lawyer. You learned that Jennifer Walters is in your city
representing super humans who may unintentionally leave a mess behind from saving the day.
You dial the number 1-877-SHE-HULK. You connect with the operator who sounds like Jennifer
Walters telling you all of the services that the Superhuman Law Division at GLK&H offers. Write
Figure 2: Table for problem 2 that shows the message for each option.
a user defined function called greenLawyer that displays the list of options, allows the user

result of the option selected.
to select one, and then display the result. If none of the values match, then the message “I’m
sorry. I don’t recognize that super being option.” is displayed to the terminal window. Inside the
user defined function you will display a welcoming message and list the options for the user.
Figure 3 shows a sample text to be displayed as the welcoming message along with selecting
the output and the result. Make sure it is exact to receive potential credit as the script will check
for it. You must also use a switch statement for this question to receive full points. If a
switch statement is not used then the highest mark you can receive is half mark on the
rubric evaluation.
Problem 3
Write a user defined function definition called coordinates that takes x-y coordinates of a
point in the Cartesian plane and prints a message telling either an axis on which the point lies
or the quadrant in which it is found.
Figure 4: Quadrants in the 2D coordinate plane.
The user defined function takes two double arguments and doesn’t return anything. Hint:
Don’t forget x-axis, y-axis and origin. The coordinates are collected in the main function. The
following figure shows a sample output. Make sure the output matches for the script to receive
credit. The values of the coordinates must be displayed up to two decimal places.

Problem 4
You are working for a architecture company that loves designing triangle shape buildings. The
company has grown that they are able to create their own software to perform some blue print
designs rather than having someone design manually by hand. Part of the software is configuring measurements to ensure that the potential building is in the shape of a valid triangle.
Figure 7 shows the geometric definition of what determines a shape to be a valid triangle. Using
Figure 6: The triangle and its properties of validation.
these properties, write the definition of a user-defined function called triangle. The function
has three parameters that are all integer type. Each parameter represents the length of the
side. Assume that the input is always collected in abc order. Inside the main function, you will
ask the user for the length of each of the sides. Once the input is collected, you will call the
user-defined function and perform the respective operation that was asked in this problem. The
function will display the logistics it is checking to determine if the values represent a triangle
or not. The function also returns an integer value which represents the outcome. The value
1 returned means the shape is a valid triangle. The value -1 means otherwise. Using those
values, you will then display the outcome message in the main function. If the value is 1, then
“Triangle!” is displayed. Otherwise display “Not Triangle!”. The following figure shows a sample
output of what the python script expects. Make sure to have it exact in terms of white space,
newlines, and characters or else the script will mark it wrong.
