Display a Circular Singly linked list

We can display the data of the circular singly linklist in two process

1. Front to end
2. End to front

We can easily program it using recursive function

#include<stdio.h>
#include<conio.h>
struct linklist
{
	int i;
	struct linklist *next;
};
typedef struct linklist node;

//prototype declaration

void ftol(node *,node *);
void ltof(node *,node *);

node *head;
int main()
{
	int c,i,pos;	
	while(1)
	{
		printf("2. First to last display\n");
		printf("3. last to First display\n");
		printf("15. Exit\n");
		printf("Enter Your choice : ");
		scanf("%d",&c);
		switch(c)
		{
			case 2:
				ftol(head,head); // First to last display
				break;
			case 3:
				ltof(head,head); // last to First display
				break;
			case 15:
				exit(0);
				
		}
	}
	return 0;	
}

void ftol(node *l,node *h)
{
	if(l->next!=h)
	{
		printf("%d\n",l->i);
		ftol(l->next,h);
	}
	else
	{
		printf("%d\n",l->i);
	}
}
void ltof(node *l,node *h)
{
	if(l->next!=h)
	{
		ltof(l->next,h);
		printf("%d\n",l->i);
	}
	else
	{
		printf("%d\n",l->i);
	}
}
