Question
Circular linked list is a form of the linked list data structure where all nodes are connected as in a circle, which
means there is no NULL at the end. Circular lists are generally used in applications which needs to go
around the list repeatedly.
struct Node * insertTONull (struct Node *last, int data)
// This function is only for empty list

struct Node insertStart (struct Node +last, int data)
In this question, you are going to implement the insert functions of a circular linked list in C. The
Node struct, print function and the main function with its output is given below:
struct Node
{
int data;
struct Node *next;
};
struct Node insertEnd (struct Node *last, int data)
void print(struct Node *tailNode)
struct Node *p;
if (tailNode -- NULL)
struct Node * insertSubseq (struct Node *last, int data, int item)
puts("Empty");
return;
p - tailNode → next;
do{
printf("%d ",p→data);
p - p > next;
while(p !- tailNode →next);
void main(void)
{
struct Node *tailNode - NULL;
tailNode - insertTONull(tailNode, 6);
tailNode - insertStart(tailNode, 4);
tailNode - insertEnd (tailNode, 8);
tailNode - insertEnd (tailNode, 12);
tailNode - insertSubseq(tailNode, 9, 8);
Output:
4689 12
print(tailNode);
Please follow the rules given below:
• Take an external pointer which points to the iast node of the list, not the head. This will
help you to easily insert in the beginning or at the end of the list.
• Fill the functions given below.
• If the given search argument cannot be found in the list, insertSubseg function should
issue an error message.
