ECE $1400$ Final Project Requirements $$ Fall $2024$

Task

You are to create a C program that reads English text $($i$.$e$.$ words$)$ from an input text file and

writes a sorted list of words and their frequencies of appearance to an output text file.

Requirements

$1.$ The program will be graded using Cygwin and gcc$.$

$2.$ The input file will contain a sequence of English words with each word separated by whitespace

$($spaces$,$ tabs$,$ or newlines$).$ Each line of the output file shall contain one $($right$-$justified$)$ word, a

space, and the number of times the word appears.

$3.$ All words in the input file will $20$ characters or less in length. There is no limit to the size of the

input file.

$4.$ The words in the output file must be sorted in ascending order $($alphabetical$).$

$5.$ Each word in the input file shall only appear once in the output file.

$6.$ The program must be named wordCount.exe and source files must be called

wordCount.c$,$ myLinkedList.h$,$ and myLinkedList.c$.$ Include a makefile for building

your program. Submit a single zip file that includes your source code and makefile. Do not zip a

folder, only the individual files.

$7.$ The program will expect $2$ command$-$line arguments to specify the names of the input and

output files. You MAY NOT hard$-$code the file names into your program. Example command$-$

line input:

$ $.\backslash$wordCount$.$exe input.txt output.txt

$ $.\backslash$wordCount$.$exe my$\_$input.txt my$\_$output.txt

$8.$ Missing information on the command line and$/$or failure to open input or output files shall result

in an error message and program termination.

$9.$ Words and frequencies must be stored in a sorted linked list. You must use dynamic memory

allocation. You MAY NOT use an array.

$10.$ Remember function headers, pseudocode, and the $80-$character line limit$!$

Example Files

If the input file looks like this:

we the people of the united states in order to form

a more perfect union

establish justice

insure domestic tranquility

provide for the common defence

promote the general welfare

and secure the blessings of liberty

to ourselves and our posterity

do ordain and establish this constitution

for the united states of america

The associated output file should look like this:

a $1$

america $1$

and $3$

blessings $1$

common $1$

constitution $1$

defence $1$

do $1$

domestic $1$

establish $2$

for $2$

form $1$

general $1$

in $1$

insure $1$

justice $1$

liberty $1$

more $1$

of $3$

ordain $1$

order $1$

our $1$

ourselves $1$

people $1$

perfect $1$

posterity $1$

promote $1$

provide $1$

secure $1$

states $2$

the $6$

this $1$

to $2$

tranquility $1$

union $1$

united $2$

we $1$

welfare $1$

Notice that the output file contents are in alphabetical order with words right$-$justified. Think

about different input file scenarios and craft appropriate input files to test those scenarios.
