一个简单的C语言作业!

把源程序给你吧。

#includestdio.h

#includemalloc.h

typedef struct node

{ int num;

struct node *next;

}linklist;

主程序如下:

#include"h1.h"

/* 建立单循环链表函数 */

linklist *creat(int n)

{

int k;

linklist *head, *r, *p;

p=(linklist *)malloc(sizeof(linklist));

head=p;

p-num=1;

printf("输入第一个人的密码:\n");

scanf("%d",p-cipher);

r=p;

p-next=p;

for(k=2;k=n;k++)

{

p=(linklist *)malloc(sizeof(linklist));

p-num=k;

printf("输入密码:\n");

scanf("%d",p-cipher);

r-next=p;

r=p;

}

p-next=head;

return(head);

}

/* 选择出列编号 */

linklist *select(linklist *head, int m)

{ linklist *p,*q;

int k;

q=head;

k=1;

p=q-next; //q为p的前趋指针,p指向当前报数的人

while(q!=p)

{

k=k+1; //报一次数

if(k%m==0)

{ printf("出列的序号为:%d\n",p-num);

m=p-cipher;

q-next=p-next; //对应的结点从链表中删除

free(p);

k=0;

p=q-next;

}

else{

q=p;

p=p-next; // p指向当前报数的人

}

}

head=p;

return(head);

}

void main()

{ int n,m;

linklist *head;

printf("Input n:\n");

scanf("%d",n);

printf("Input the number to call:\n");

scanf("%d",m);

head=creat(n);

head=select(head,m);

printf("The last one is:%d\n",head-num);

}
