C Programming

Traversing a linked list

	/* Program to illustrate traversing a list */
	#include <stdio.h>
	struct list {
		int         value;
		struct list *next;
	};

	main()
	{
		struct list n1, n2, n3, n4;
		struct list *list_pointer = &n1;

		n1.value = 100;
		n1.next = &n2;
		n2.value = 200;
		n2.next = &n3;
		n3.value = 300;
		n3.next = &n4;
		n4.value = 400;
		n4.next = 0;


		while( list_pointer != 0 )  {
			printf("%d\n", list_pointer->value);
			list_pointer = list_pointer->next;
		}
	}

This program uses a pointer called list_pointer to cycle through the linked list.
