as simple as it needs to be and not any simplier

Hi,
I'm working on extra credit. The thing is the extra credit is different from my assignments in that it is way more general of a description of the program to be written. I thought it would be good to ask before I got to crazy so I can make things easier on myself in the long run.
I'm to write a phone directory program. It reads first name, last name, address, and phone number. It diplay's a menu to the user.
[A]dd entry to phone directory
[D]elete an entry
[U]pdate an entry
[L]ist the entire phone directory
[E]xit the menu
Then it goes on the describe a little bit of the program and what happens if they choose A and so forth. I'm not so worried about that part. This is part which concerns me
The directory should not have more than 5 records. Those records should be read from another file and filled into parallel arrays. Note the directory must be sorted by last name when listed.
Now this becomes difficult for me because I haven;t used parallel arrays before.
And the sorted alphabetic part concerns me in regards to the arrays how would I keep them in order?
So I started messing around on how to actually get my information first. This is just an idea code I would take the code out off all the functions and put it into one function. This seems like I may be doing things the hard way check out my code and see the idea if there is an easier way while meeting the requirements for the assignment please let me know. Main is just to test to see if the function got what it was supposed to get. I feel like I do things the hard way with programming sometimes so I'm curious to bounce the idea out there and see what people think.
Thanks
