The realization and operation of C-language one-way link list __c language

Recently fascinated by the C language, deliberately borrowed a book on the C language algorithm fine solution, the book has a lot of good code, learn to share to everyone.

Here are all the source code in the blog: GitHub Project address

#include <stdlib.h>
#include <string.h>
#include <stdio.h>

#define LEN sizeof (struct node)

struct node
{
	int data;
	struct node *next;

int main (int argc, char const *argv[]) {
	struct node *p, *PL, *head;

	Head = p = (struct node *) malloc (LEN);
	scanf ("%d", &p->data);
	/* Replace EOF into input 0 when terminating the input to the list *
	/while (p->data!= 0) {
		PL = p;
		p = (struct node *) malloc (LEN);
		scanf ("%d", &p->data);
		Pl->next = P;
	}

	P->next = NULL;
	p = head;

	printf ("List number is:");

	/* The pointer to the element in the list is not NULL, the elements in the cyclic output list *
	/while (P->next!= NULL) {
		printf ("%d\n", p->data);
		p = p->next;
	}

	printf ("%d\n", P->data);
}

If there are deficiencies in the above code, I hope you will criticize me.
