Each link in the link list is a structure which contains (besides other data) a pointer to another structure of the same type (struct *). Each "struct *" points to the next link in the link list.
Each link must be allocated using the malloc( ) function.
Here's an example program that creates a link list of TS cases.
Here's how LinkListExample.c runs:
UNIX prompt >> a.out
Enter customer's last name: Tyler
Enter Case ID : 123456
Enter status (no gaps) : open
Here's the Link List
####################

Options:
(1) Add another case to the front the Link-List.
(2) Remove a case from the Link-List.
(3) Quit!
Select an option: 1
