Given the following definitions that we have used in class to represent a doubly-linked, circular List with a dummy-header node that contains data of type "struct Student". typedef struct { char *name; char *major; } Student; typedef struct node { Student *data; struct node *next; struct node *prev; } Node; typedef struct { Node *header; int size; } LinkedList; LinkedList *roster; Here is a picture of what the Linked List might look like, although you should answer the following question for a general list (ie, that does not necessarily contain 3 data items). What TYPE of data is the following: roster->header->data->next->next Group of answer choices int int * Node Node * Student Student * char char * This is legal code, but it does not match any of the types listed above. This is illegal code, and would produce a syntax error.

Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
Question
Given the following definitions that we have used in class to represent a doubly-linked, circular List with a dummy-header node that contains data of type "struct Student".
typedef struct { char *name; char *major; } Student;
typedef struct node { Student *data; struct node *next; struct node *prev; } Node;
typedef struct { Node *header; int size; } LinkedList;
LinkedList *roster;
Here is a picture of what the Linked List might look like, although you should answer the following question for a general list (ie, that does not necessarily contain 3 data items).
What TYPE of data is the following: roster->header->data->next->next

This is legal code, but it does not match any of the types listed above.
This is illegal code, and would produce a syntax error.
