[Solved] CptS 122 Lab #2: Linked Lists

Along with vectors, linked lists are one of the fundamental data structures in computer science. Unlike vectors, which store information in a contiguous block of computer memory, linked lists have the potential to store information in non-adjacent memory blocks. In this lab, you will write a very basic doubly-linked list. To complete this lab, you will need to have created the appropriate .h and .c files that implement the following struct and functions:typedef struct IntList_t{int value;struct IntList_t *previous;struct IntList_t *next;} IntList_t;IntList_t* intList_init(int starting_value)Like our vectors init function, the LL version must dynamically create a new IntList_t and set its starting value as well as setting the previous and next pointers to NULL.IntList_t * intList_rewind(IntList_t *some_list)This function returns a pointer to the beginning of the linked list. For our purposes, we will consider the beginning of a linked list to be represented by the IntList_t whose previous pointer is equal to NULL.void intList_add(IntList_t *some_list, int value)This function will add a new IntList_t to the end of the current linked list. Note that for our purposes, the last element in the list is represented by the individual IntList_t whose next pointer is equal to NULL.void intList_remove(IntList_t *some_list)This function removes the supplied IntList_t from the current chain of list items.void intList_free(IntList_t *some_list)Freeing up dynamic memory allocated for a linked list is a little more work than freeing up dynamic memory for a vector. As such, this function should call free on every node in the linked list.Sample OutputTo test these methods, you must write a simple test driver in your main function. Here is an example of my test driver:
