😁 I have nothing to say more to Pradeep - C Guru here. But yes as a kick start you must be knowing the concepts of linked lits, first try understanding pointers and how memory locations are accesesed with pointers.
Then linked list is all about playing around with these pointers. -

Check this program. I think this will help you.

struct node
{
int data;
struct node *link;
};
struct node *insert(struct node *p, int n)
{
struct node *temp;
/* if the existing list is empty then insert a new node as the
starting node */
if(p==NULL)
{
p=(struct node *)malloc(sizeof(struct node)); /* creates new node
data value passes as parameter */
if(p==NULL)
{
printf("Error\n");
exit(0);
}
p-> data = n;
p-> link = p; /* makes the pointer pointing to itself because it
is a circular list*/

temp = p;

it */

temp = temp-> link;
