Binary Search Tree problem (too)

<< Split from http://cboard.cprogramming.com/c-pro...e-problem.html >>

Hello. I have a problem with the project below. I started doing some things but because I'm not experienced at programming, I would like to help me to resolve to have it ready by Friday which I sumbit to the systems of my school. Sorry for my English but I am from Greece and the anxiety now affect.

Information on each antenna connections stored in binary
search trees (binary search trees) that will allow the introduction
insertElement and deletion removeElement telephone {number, eventNo}. As
considered key to the phone number. So for each node of the tree
telephone numbers of the left sub-tree is smaller than the number
phone hub and phone numbers of the right sub-tree
older. No need to write code to keep the tree
balanced. Information on each antenna connections stored in a table
fragmentation. To use the key number. When
more than one key corresponding to a position of hash table
then the corresponding objects placed in a binary tree.

If you need to make some extra things that will be right you have the ok from me...
Please help! I'm desperate...

I forgot to mention that the project consists of 3 phases. The one you sent was read aloud before the third. I've done some things in the first 2 phases on which i will send you to look.
the first project was :The first delivery planned, a table stored
information on the antennas of mobile communication system. Information
for the neighbors as well as information on each antenna connections
stored in the form of doubly linked lists.
and the second project was: The second deliverable information for the connections of each antenna is stored in
a hash table. For the key used phone number.
When more than one key corresponding to a position in the table
hash then the corresponding objects placed in a connected
list.

THANK YOU AGAIN!
