UC知道帮忙看下这c程序哪里错了

两个地方需要修改：
1. find函数中while(current->next!=NULL)改为while(current）
2. 把main函数中的p->next=NULL删除，p即是链头。
最好再添加一个清理函数，如：
void clear(struct student *p)
{
struct student *cursor = p;
while (cursor)
{
p = p->next;
free(cursor);
cursor = p;
}
}

FILE *stream;
if((stream=fopen("d:\\ghost.dat", "w+"))==NULL)
{
perror("磁盘错误无法写入");
exit(1);
