#define N 6

#include<stdio.h>

typedef struct studen

int rank;
int average;

STU *read()
{
FILE *fp;
STU *student
student=(STU *)malloc(6*sizeof(STU));
if((fp=fopen("9-20.dat","r"))==NULL)printf("Open file erro!\n");
fread(student,sizeof(STU),6,fp);
fclose(fp);
return(student);
}
void printf(char *name,STU *student1)
{
int i=0;
while(name!=student1.name)
{
student1++;
i++;
if(i>7){printf("NO nanme\n");break;}
}
printf("Name :%s\n",student1.name);
printf("Rank :%d\n",student1.rank);
printf("Average:%d\n",student1.average);
}
main()
{
char name[20];
STU student1[N];
student1=read()
首先，这里
STU *read()
{
FILE *fp;
STU *student
后面没有分号，不知道是不是粘贴的问题
第二，函数
void printf(char *name,STU *student1)
student1是一个STU类的指针，所以后面不能用"."符号，要用"->"符号，所有的student1所拥有的对象，比如
student1.name 改成 student1->name
然后函数
void printf(char *name,STU *student1)
你是想写
void print(char *name,STU *student1) 吧？估计是笔误。
最后，main()里最好用指针来赋值
