~~TOC~~
This section will document any updates applied to the project since original release:
This is a transitional project, making a few modifications to the list struct forcing some changes to a few functions so that we can better explore the next topic (in sll4).
As such, while this is a standalone project, it should be considered a small one, and one that is given out in combination with another (again: sll4), so be mindful of time management.
You will need to complete this project prior to upgrading to sll4.
For this project, we need to make a couple modifications to the list struct (which you can also check out in inc/list.h):
struct list { Node *first; // pointer to start of list Node *last; // pointer to end of list struct list *after; // pointer to the next list unsigned long int qty; // number of nodes in list }; typedef struct list List; // because we deserve nice things
Specifically, we have an after pointer, so that we can point to an entirely separate list, along with a newly added qty variable, which will keep track of the number of nodes in the list.
To implement qty, all list functions that perform manipulations to the list will need to see some updating (insert(), append(), obtain(), cplist(), and mklist()).
mklist() should also set the list's after pointer to a sane initial state (NULL).
To assist you in verifying a correct implementation, a fully working implementation of the node library, list library (with new modifications), and group library should resemble the following:
Here is what you should get for the specific functions relevant to sll3:
lab46:~/src/data/sll3$ make check ====================================================== = Verifying Singly-Linked List Functionality = ====================================================== [mklist] Total: 21, Matches: 21, Mismatches: 0 [cplist] Total: 14, Matches: 14, Mismatches: 0 [insert] Total: 21, Matches: 21, Mismatches: 0 [append] Total: 21, Matches: 21, Mismatches: 0 [obtain] Total: 44, Matches: 44, Mismatches: 0 ====================================================== [RESULTS] Total: 121, Matches: 121, Mismatches: 0 ====================================================== lab46:~/src/data/sll3$
Here is what you should get for all the functions completed so far in the list library (sll0+sll1+sll2+sll3):

When you are done with the project and are ready to submit it, you simply run make submit:
lab46:~/src/data/PROJECT$ make submit ...
To be successful in this project, the following criteria must be met:
