为什么出错了？什么原因？？
#include <stdio.h>
#include <malloc.h>
#include <string.h>
struct stu{
int num;
char name[20];
char sex;
float score;
}student[2]={{050101, "许元元 ", 'w ',502},{050102, "张帆 ", 'm ',498}};

typedef struct node{
struct stu data;
struct node *next;
}Llist,*linklist;

createList(linklist p,struct stu student[],int n)
{linklist h=NULL;
int i;Llist *s,*r;
for(i=0;i <n;i++)
{s=(Llist *)malloc(sizeof(Llist));
s-> data.num=student[i].num;
strcpy(s-> data.name,student[i].name);
s-> data.sex=student[i].sex;
s-> data.score=student[i].score;
s-> next=NULL;
if(h==NULL){h=s;r=s;}
else{r-> next=s;
r=s;}
}
}
main()
{Llist *a1=NULL,*p;
createList(&a1,student,2);
p=a1;
while(p)
{printf( "\n%d\t%s\t%c\t%f ",p-> data.num,p-> data.name,p-> data.sex,p-> data.score);
p=p-> next;
}

}

[解决办法]
createList(a1,student,2);
p=a1;
参数类型不对，改成上面的试试
[解决办法]
1, createList()前面应该加个void

2, 你函数的原型是: void createList(linklist,struct stu *,int)

你调用时:createList(&a1,student,2);
变成了:void createList(linklist *,struct stu *,int)

本身已经是指针了, 再取地址干吗?
