Sample Linked List Operations ,[object Object],[object Object],[object Object],[object Object],ListStart = (EPtr) malloc(sizeof(EStruct)); /* ListStart points to memory allocated at location 108 */

Sample Linked List Ops (cont) ,[object Object],ListStart->next = (EPtr) malloc(sizeof(EStruct)); ListStart->next = NULL; ListStart->next->data = 9; ListStart->next->next = NULL;

Sample Linked List Ops (cont) ListStart->next->next = (EPtr) malloc(sizeof(EStruct)); ListStart->next->next->data = 6; ListStart->next->next->next = NULL; /* Linked list of 3 elements (count data values): ListStart points to first element ListStart->next points to second element ListStart->next->next points to third element and ListStart->next->next->next is NULL to indicate there is no fourth element */

Sample Linked List Ops (cont) /* To eliminate element, start with free operation */ free(ListStart->next->next); /* NOTE: free not enough -- does not change memory Element still appears to be in list But C might give memory away in next request Need to reset the pointer to NULL */ ListStart->next->next = NULL; /* Element at 132 no longer part of list (safe to reuse memory) */
