CSE 240 Spring 2021 Homework 7:
Linked List of Containers (50 points)
Due Saturday, March 13, 2021 at 11:59PM, plus a 24-Hour grace period
Introduction
The aim of this assignment is to make sure that you understand and are familiar with the
concepts covered in the lectures, including linked list, pointer operations, and parameter
passing mechanisms. This two-assignment combination allows you to put all together that you
have learned in C programming language into a large program. By the end of the assignment,
you should have understood and exercised
● Pointer and pointer to pointer operations accessing structured data
● Linked list of structures, with complex manipulations of pointer and structure
● Different types of parameter passing mechanisms and return values of different types.
● Solving problems in recursion
Reading: Textbook Chapter 2, Section 2.5.4 on linked list and Section 2.6 on parameter passing
and Section 2.10.
Preparation: Complete the multiple choice questions in the textbook exercise section. The
answer keys can be found in the course Web site. These exercises can help you prepare for your
weekly quiz and the exam. You are encouraged to read the other exercise questions and make
sure you understand these questions in the textbook exercise section, which can help you
better understand what materials are expected to understand after the lectures and homework
on each chapter.
You are expected to do the majority of the assignment outside of class meetings. Should you
need assistance, or have questions about the assignment, please contact the instructor or TA
during their office hours.
You are encouraged to ask and answer questions on the course discussion board. However, do
not share your answers and code in the course discussion board.
Homework Description
The following figure shows an instance of the linked list that you will be building and managing
in these two homeworks. The node of the main linked list ‘list’ is called libraryList, which
contains two members: (1) book member is a pointer to the book node, (2) a pointer to next
libraryList node. The book node contains three members: (1) book title, (2) aisle number, and
(3) a pointer to bookType list. The node in the bookType list has two members: (1) book type (2)
a pointer to next bookType node.

libraryList
HW 7 Programming Assignment (50 points)
You are given a partially completed program hw7.c. You should follow the instructions given in
the program to complete the functions so that the program executes properly. You will be
completing a program that creates a list of books. It is a menu driven program where user is
given following options:
a) Add an book’s information (Book title and aisle number) is already implemented. The
new book is added to the head of the linked list. We do not ask user for bookTypes to
add in this function. So simply NULL is assigned to *bookType member of the ‘book‘
node when a new book is added to the list in this function. (Note: *bookType is used in
further functions)
b) Display the book list is already implemented. This function prints each book’s title and
aisle number. It does not print bookType of the book.
These functions need to be implemented:
c) Search a book in the list by book title. It prints if the book exists on the list or not. This
function should return the ‘book‘ node if that book is found in the list, else return NULL.
It is used as a helper function in executeAction() to check if the book exists in the list.
The next part focuses on using ‘bookType’ linked list. In this part, the user should be able to use
the following menu options:
a) Add a bookType to an book’s profile. This function assumes that the book is added in
the list and assigns book type using the *bookType member of ‘book’ node. You may
add the new bookType to the head or tail of the ‘bookType’ linked list. (Sample solution
adds the bookType to the tail)

b) This function prompts the user to input a book type. Then it displays the list of books
that have the entered book type only. Lastly, it should display the number of books that
met this requirement. This function should display both book’s title and aisle number.
See expected output below.
c) Removes the book from the list. This function removes the book’s title, aisle number
and bookType list of the book when removing the book from the list.
Expected outputs:
addBook (already implemented)

Homework 07
displayLibraryList (already implemenetd)
(New books are added to the head of ‘list’. So newer books appear first. Not necessary to print
‘end of list’ message.)
searchBook (5 points)

addBookType (15 points)
displayBookTypeList (15 points)
( Sapiens recently added book type as ‘Nonfiction’ which was added to tail of her *bookType
list. So, it’s name appears when ‘l’ option is used ).

removeBook (15 points)
(After removing a book, you should use the display option to verify it functioned correctly)
What to Submit?
You are required to submit your solution in a compressed format (.zip). Make sure your
compressed file is label correctly - lastname_firstname7.zip. (All lowercase, do not put
anything else in the name like "hw7".)
The compressed file MUST contain the following:
hw7.c (completed code)
No other files should be in the compressed folder.
If multiple submissions are made, the most recent submission will be graded. even if the
assignment is submitted late.
Submission preparation notice: The assignment may consist of multiple files. You must copy
these files into a single folder for canvas submission. To make sure that you have all the files
included in the zip file and they work after unzip operation, you must test them before
submission. You must also download your own submission from the canvas. Unzip the file on a
different machine and test your assignment and see if you can open and test the files in a
different location, because the TA will test your application on a different machine. If you
submitted an empty project folder, an incomplete project folder, or a wrong folder, you cannot
resubmit after the submission linked is closed! We grade only what you submitted in the canvas.

Homework 07
We cannot grade the assignment on your computer or any other storage, even if the modification
date indicated that the files were created before the submission due dates. The canvas submission
may take a few minutes. Be patient and wait for it to complete.
Where to Submit?
All submissions must be electronically submitted to the respected homework link in the course
web page where you downloaded the assignment.
Late submission deduction policy
● No penalty for late submissions that are received within 24 hours after the deadline;
● 10% grade deduction for every day it is late after the grace period;
● No late submission after Tuesday at 11:59PM.
Grading Rubrics
Each sub-question (programming tasks) has been assigned certain points. We will grade your
programs following these steps:
(1) Compile the code. If it does not compile, 50% of the points given for the code under
compilation will be deducted. Then, we will read the code and give points between 50%
and 0, as shown in right part of the rubric table.
(2) If the code passes the compilation, we will execute and test the code using test cases. We
will assign points based on the left part of the rubric table.
(3) In both cases (passing compilation and failed compilation), we will read your program and
give points based on the points allocated to each sub-question, the readability of your code
(organization of the code and comments), logic, inclusion of the required functions, and
correctness of the implementations of each function.
(4) Please notice that we will not debug your program to figure out how big or how small the
error is. You may lose 50% of your points for a small error such missing a comma or a
space!
(5) We will apply the following rubrics to each sub-question listed in the assignment. Assume
that points assigned to a sub-question is pts:
Major Code passed compilation Code failed compilation
Please read the FAQ file in the Course Information folder:
Q: For some reason, my assignment submission did not go through, but I thought it went
through. I can show you on my local disk or in my Dropbox that I completed the assignment
before the due date. Can my assignment be graded?
A: You should always download your own submission from the blackboard after submission and
test if the submission contains all the required files. We will grade the assignment submitted to
Canvas only. We cannot grade the assignment sent from email or stored in any other places,
regardless its last-modified-time. If you submitted your assignment into the blackboard, it cannot
be downloaded from the instructor side, but it can download from your side, we can download
from your blackboard and grade the assignment. Please meet the instructor or TA in this case.
