Description:
Part A
In this part you are to write a C program which mimics the functionality of a friends list. A
friends list is often used by users on hosts to identify if any friends are logged on at the same
time.
A friends list should always report the name of the friend, the username of the friend, the time
the friend logged onto the host, whether or not the friend accepts talk sessions and where the
friend is logged on from (normally the name or address of a computer). An example piece of
output would be:
UserID Name Talk Login Time Location
joey Joe Blogg No Mon 9:20 wumpus.its.uow.edu.au
fish Fish Man Yes Mon 0:30 yoshi.cs.uow.edu.au
To generate this friends list you are going to use the program finger. The output from the finger
program should be taken and piped into your program. Using this information as the basis you
perform the following steps.
Step 1.
Write a C source file and header which is used to implement a linked list. The files should be
named linkedlist.c and linkedlist.h. Your linked list should only need an insert and find/search
function. The find/search function will print nodes and associated data for keys that match. The
key is username.Each node of the linked list should contain the following information deemed essential to solve
the friends list problem.
struct linkednode
{
char* realname; // the person real name from the NAME field
char[9] username; // the person username from the LOGIN field
int talk; // does the person accept talk sessions
int idle_time; // the idle_time in minutes from the IDLE field
char* where; // the persons location from the WHERE field
char* logintime; // The login time from the WHEN field.
};
Each node should also contain information essential to the management of the list (think about
how linked lists are represented in code).
Once you have implemented your linked list, using a similar node structure to the one above,
write a simple driver program called main.c, which populates the list with arbitrary data and can
search the list for a particular user (search is based on the username). The search should report
ALL nodes which are related to that user and all information kept in them. The search is
performed on the key username. You do not need to submit this main.c file.
Step 2.
The finger program generates the following output;
$ finger

| Ready to START ASAP!
I find this project very nice. I just love pure 'C' programming for Unix. And if you look at my projects list (in resume) you'll see that I do projects of exactly this kind!
It will be done (coded & tested) by 1:00 am (this night).
As usual I will send you fisrt available alpha version so you can review coding style, density of comments and stuff like that.
Sincerely yours,
Paul
