Now that you have had the experience building a program that demonstrated using a singly linked list that held integers, you will now produce a program that holds other kinds of data that we read from a file. We are doing so to demonstrate how little changes, other than your test software and the definition of what UserData is composed of$!$

The Solution Steps:

$1.$ Create a project by copying the provided $4$ files into a project, building it and running it$.$ The files are:

a$.$ UserData.h $$ this file defines what each node contains

b$.$ LinkedList.h $$ this file contains the declarations of the linked list functions

c$.$ SinglyLinkedList.c $$ this file is the implementations of all of the singly linked list functions

d$.$ LinkedListTester.c $$ this file contains the implementation of a test routine for the linked list functions.

$2.$ We will be handling data in our linked list that consists of an integer and a character string. Modify the UserData structure so that it looks as follows:

typedef struct

$\{$

int importance;

char taskName$[80]$;

$\}$ UserData, $*$UserDataPtr;

$3.$ Place the following test data in a file. You can name the file whatever you want, but I would suggest something like "testData.txt$".$

$1$ task$1$

$2$ task$2$A

$3$ task$3$A

$2$ task$2$B

$4$ task$4$A

$4$ task$4$B

$3$ task$3$B

$4.$ Your test program will be a modified version of LinkedListTester.c$.$ It must be modified to read in the data from a file instead of using the initialized array of integers to hold the data. Note that each line in the file contains an integer and a task name $($no spaces in the task name$),$ so reading is probably best done using a $\%$d $\%$s$$ format. What else
