在头部加入   #include   "stdafx.h"就可以了，给你个建议，以后写代码时注意工整性，方便检查

老实说，你的代码风格不行啊

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

int main()
{
    struct film
    {
        int i;
        struct film *next;
    };
    
    //链表输入数据
    struct film *head, *last, *ptr;

    head = last = (struct film*) malloc(sizeof(struct film));

    int i;
    while(scanf("%d", &i))    //你不觉得这里会无限循环么
    {
        ptr = (struct film*) malloc(sizeof(struct film));
        last->next = ptr;
        last = ptr;
        last->i = i;
    }
    
    //下面是查找链表中大于8的数删除; 
    struct film *p,*f;
    p = head;
    f = head->next;
    while(f)
    { 
        if(f->i > 8)
        {
            if(f->next == NULL)
            {
                p->next = NULL;
                free(f);
            }
            else
            {
                p->next = f->next;
                free(f);
            }
        }
        p = f;
        f = f->next;
    } 

    //下面是输出; 
    ptr = head->next;
    while(ptr)
    {
        printf("%d", ptr->i);
        ptr = ptr->next;
    }
    
    //下面清空 
    ptr = head;
    while(ptr)
    {
        ptr = head->next;    //head是最后一个节点时，这句会报错的
        free(head);
        head = ptr;
    }
    return 0;
}

没有,不是这样,你们看看查找删除那部分,应该是那里错了,不要那部分的话就可以正常输入输出的

哎,高手,出来个好不好

#include<stdio.h>
#include<stdlib.h>
#include<malloc.h>
struct film{
    int i;
    struct film *next;
        };//链表输入数据
main()
{

    struct film *head,*last,*ptr;
    head=last=(struct film*)malloc(sizeof(struct film));
    int i;
    scanf("%d",&i);
    while(1)//修改了循环条件
    {
      ptr=(struct film*)malloc(sizeof(struct film));
      last->next=ptr;
      last=ptr;
      last->i=i;
      scanf("%d",&i);
      if (i==0)
          break;
    }//下面是查找链表中大于8的数删除;
    last->next=NULL;//你主要是这句没有


    struct film *p,*f;
    p=head;
    f=head->next;
    while(f!=NULL)
    {
        if(f->i>8)
   
        {
            if(f->next==NULL)
   
            {
                p->next=NULL;
   
                free(f);
                break;
               
            }
        
        
            else
   
            {
                p->next=f->next;

                free(f);
            }
            f = p->next;
        }
        else
        {
            p = f;
            f = f->next;
        }


   
   
    }
     //下面是输出;
    ptr=head->next;
    while(ptr)
    {
        printf("%d/t",ptr->i);
        ptr=ptr->next;
    }//下面清空
    ptr=head;
    while(ptr)
    {
        ptr=head->next;
   
        free(head);
   
        head=ptr;
        
    }
    return 0;
  }
