[数据结构与算法]我的第一个循环链表

代码如下：

#include <stdio.h>
#include <stdlib.h>
typedef struct
{
	char id[300];
	char password[300];
}Elemtype;
struct LNode
{
	Elemtype data;
	struct LNode *next;
};
int main(int argc, char *argv[])
{
	struct LNode boy;
	strcpy(boy.data.id,"password");
	strcpy(boy.data.password,"1");
	struct LNode boy2;
	strcpy(boy2.data.id,"password2");
	strcpy(boy2.data.password,"2");
	struct LNode boy3;
	strcpy(boy3.data.id,"password3");
	strcpy(boy3.data.password,"3");
	struct LNode boy4;
	strcpy(boy4.data.id,"password4");
	strcpy(boy4.data.password,"4");
	boy.next=&boy2;
	boy2.next=&boy3;
	boy3.next=&boy4;
	boy4.next=&boy;
	struct LNode *boy5;
	boy5=&boy;
	int a;
	for(a=0;a<8;a++)
	{
		printf("%s\t%s\n",boy5->data.id,boy5->data.password);
		boy5=boy5->next;
	}
	system("pause");
	return 0;
}

程序运行结果如下：
