链表数据读取问题
程序代码：
//头文件
#ifndef _HEAD_
#define _HEAD_
#define NSIZE 45
struct film{
char title[NSIZE]; //用于存放电影名
int rating; //评分
};
typedef struct film Film;
struct node{
Film item;
struct node *next; //指向下一节点的指针
};
typedef struct node NODE;
typedef NODE* LIST;
void initialization (LIST *pfile); //初始化链表
bool listisfull(void); //没什么用
void additem(LIST* pfile,Film list); //向链表尾部添加数据
void cleanlist(LIST *pfile); //释放链表
void copystr(Film film,LIST pfile); //将数据存入节点
int showlist(LIST pfile); //显示数据
#endif
//主函数
#include<stdio.h>
#include<stdlib.h>
#include"head.h"
int main(void)
{
Film list;
LIST movies;
initialization (&movies); //初始化
printf("please enter the title of movie\n");
while((gets(list.title)!=0)&&(list.title[0]!='\0'))
{
puts("enter your grade(0~10)");
scanf("%d",&list.rating);
while(getchar()!='\n')
continue;
additem(&movies,list);
listisfull();
puts("enter the title of the next film");
}
showlist(movies);
cleanlist(&movies);
puts("bye~");
return 0;
}
void initialization (LIST *pfile)
{
*pfile=NULL;
}
bool listisfull(void)
{
LIST p;
p=(LIST)malloc(sizeof(node));
if(p==NULL)
{
fprintf(stderr,"the list is already full\n");
exit(1);
}
return false;
}
void additem(LIST* pfile,Film list)
{
if(*pfile==NULL)
{
*pfile=(LIST)malloc(sizeof(node));
copystr(list,*pfile);
(*pfile)->next=NULL;
}
else
{
LIST p;
p=*pfile;
while(p!=NULL)
p=p->next;
copystr(list,p);
p->next=NULL;
}
}
void cleanlist(LIST *pfile)
{
LIST p;
while(*pfile!=NULL)
{
p=(*pfile)->next;
free(*pfile);
*pfile=p;
}
puts("clean up!");
}
int showlist(LIST pfile)
{
int count=0;
while(pfile!=NULL)
{
count++;
printf("%2d:%45s %2d\n",count,pfile->item->title,pfile->item->rating);
//问题出在printf这里，编译器一直报错。具体报错在最后
pfile=pfile->next;
}
return count;
}
void copystr(Film film,LIST pfile)
{
pfile->item=film;
}
[Error] base operand of '->' has non-pointer type 'Film {aka film}'
[Error] base operand of '->' has non-pointer type 'Film {aka film}'
请问是哪里不对，编译器的报错看不明白
