3、//去偶操作,链表中各节点按数据域递增有序链接，函数fun的功能是，删除链表中数据域值相同的节点，使之只保留一个

#include #include #define N 8 typedef struct list { int data;

struct list *next; } SLIST;

void fun( SLIST *h) {

SLIST *p,*shanchu; //用于遍历的指针p,用于删除的指针shanchu p=h->next; /p为寿元节点 while(p->next!=NULL) //终止条件 {

if(p->data==p->next->data) //判断是否有重复原素 {

shanchu=p->next;

p->next=shanchu->next; free(shanchu); } else

p=p->next; } }

SLIST *creatlist(int *a)

{ SLIST *h,*p,*q; int i;

h=p=(SLIST *)malloc(sizeof(SLIST)); for(i=0; i

{ q=(SLIST *)malloc(sizeof(SLIST)); q->data=a[i]; p->next=q; p=q; }

p->next=0; return h;

4、//在main函数中多次调用fun函数，每调用一次fun函数，输出链表尾部节点中的数据，并释放该节点，使得链表缩短。

#include #include #define N 8 typedef struct list { int data;

struct list *next; } SLIST;

void fun( SLIST *p) {

SLIST *bianli,*shanchu; //遍历，删除 bianli=p; while(bianli->next->next!=NULL) {

bianli=bianli->next;

}

printf(\ //输出

5、实现约瑟夫环函数（选做） #include #include typedef struct list { int data;

struct list *next; } SLIST;

SLIST *creatlist(int m) {

int i;

SLIST *tou,*p,*wei; //头指针 生成节点指针 尾指针 tou=(SLIST*)malloc(sizeof(SLIST)); //头节点 wei=tou;
