======Project: SLL0 APardini======

Date Set 15 February - 25 February 2015 




=====Objectives=====
In this project we create various functions that are used in multiple programs. Our purpose is to make a function library that will be accessed for this and future projects. 

=====Prerequisites=====
In order to successfully accomplish/perform this project, the listed resources/experiences need to be consulted/achieved:

  * Functions
  * Pointers
  * Structs
  * nodes
  * stacks, queues
  * etc.

=====Background=====
This project involves producing code for the following function:

  * Unordered List Itemunit-mklist.c - unit test for mklist() library function
  * unit-displayf.c - unit test for displayf() library function
  * unit-insert.c - unit test for insert() library function
  * unit-getpos.c - unit test for getpos() library function
  * unit-setpos.c - unit test for setpos() library function

=====Scope=====
Give a general overview of your anticipated implementation of the project. Address any areas where you are making upfront assumptions or curtailing potential detail. State the focus you will be taking in implementation.

=====Attributes=====
State and justify the attributes you'd like to receive upon successful approval and completion of this project.

  * attribute1: why you feel your pursuit of this project will gain you this attribute
  * attribute2: why you feel your pursuit of this project will gain you this attribute
  * etc...

=====Procedure=====

Throughout the whole break i was having difficulties accessing the info and after values on the node of the (List) call. This was due to simple placement of braces and using the pointer in the right spot. Currently able to compile but when run in program something weird happens. Within my functions i didn't add in an if function that contained the statement: if( nodeCount != NULL) This is important because the rules state if list is not NULL
=====Code=====
Upon completion of the project, if there is an applicable collection of created code, place a copy of your finished code within <nowiki><code> </code></nowiki> blocks here.
