Project: SLL3

This section will document any updates applied to the project since original release:

• revision #: <description> (DATESTAMP)

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(), 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 all the functions completed so far in the list library (sll0+sll1+sll2+sll3):
