Description
Introduction
The aim of this assignment is to make sure that you understand and are familiar with the concepts
covered in the lectures, including basic C syntax, using the strings, arrays, and multidimensional
arrays. By the end of the assignment, you should have
● understood the concepts of data, data declaration, forward declaration, and manipulation
of values stored in the memory.
● reviewed the array operations that you have learned in your previous programming classes;
● written a program using multidimensional arrays in C.
Note: Do not use pointer in this assignment. Pointer assignment will be given in the next
homework.
Reading: Textbook Chapter 2, sections 2.1, 2.2, 2.3, and 2.4, and lecture slides covered.
Exercising: Complete the multiple choice questions in Textbook Section 2.12. The answers of the
questions are available in course Web page.
You are expected to do the majority of the assignment outside the class meetings. Should you
need assistance, or have questions about the assignment, please contact the instructor or the TA
during their office hours.
You are encouraged to ask and answer questions on the course discussion board. However, do
not share your answers or code in the course discussion board. Do not cooperate with your peers
in doing the individual assignments.
Programming Assignment
For this assignment, you can use ASU General GNU GCC environment or Visual Studio. Please
specify the environment that you use at the beginning of your program:
// State the IDE that you use: Visual Studio or GCC
If you use any other environment, please test it either using GCC or visual Studio before
submission. If you do not specify the environment, the grader will use either GCC or Visual Studio,
but not both. If you program does not compile or execute correctly, your grade will be deducted.
GCC command to compile this program: gcc -std=c99 -o output hw03q1.c
Execute with: ./output

Homework 03
1. You are given hw03q1.c file, which contains a partially completed program. You are to
follow the instructions contained in comments and complete the required functions. You
will be writing functions for a program that does manipulation on 1-D and 2-D arrays. In
one part, the program defines several common operations on 2D integer arrays (AKA
matrices). In another function, you are asked to reverse one long user-input string and
then count the number of occurrences of a character in that string. Example output given
below. Go through the C file and see the sample expected output below. [50 points]

Homework 03
Note, when you create the Visual Studio project, the default location of project is similar to the
file path shown in example figure above. For your convenience, you may change the project
location while creating the project at the beginning in New Project dialog box.
Grading and 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.
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.
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!
We will apply the following rubrics to each sub-question listed in the assignment. Assume that
points assigned to a sub-question is pts:

What to Submit?
This homework assignment will have multiple parts. You are required to submit your solutions
in a compressed format (.zip). Make sure your compressed file is label correctly –
lastname_firstname3.zip. (All lowercase, do not put anything else in the name like “hw2”.)
The compressed file MUST contain the following:
hw03q1.c
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 consists 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. 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
(before Sunday midnight);
CSE240 – Introduction to Programming Language 5 | Page
Homework 03
• 10% grade deduction for every day it is late after the grace period (After Sunday);
• No late submission after Tuesday at 11:59PM.
Academic Integrity and Honor Code.
You are encouraged to cooperate in study group on learning the course materials. However, you
may not cooperate on preparing the individual assignments. Anything that you turn in must be
your own work: You must write up your own solution with your own understanding. If you use
an idea that is found in a book or from other sources, or that was developed by someone else or
jointly with some group, make sure you acknowledge the source and/or the names of the persons
in the write-up for each problem. When you help your peers, you should never show your work
to them. All assignment questions must be asked in the course discussion board. Asking
assignment questions or making your assignment available in public websites before the
assignment is due will be considered cheating.
