谢谢大家，我知道为什么了
b[i].next的问题，我把它写入student.txt之后在读出来的时候出错了
结构体成员next是指针属性，读出的时候出错了

[flyzly]

这个是我改好后的
#include<iostream.h>
#include<fstream.h>
#include<string.h>
#include<iomanip.h>
struct stu
{
char name[20];
float height;
stu *next;
};
void main()
{
stu a[100];
int i,j=0;
cout<<"姓名 身高\n";
for(i=0;i<100;i++)
cin>>a[i].name>>a[i].height;
ofstream fout("stu.txt");
if(!fout)
cout<<"文件打开失败\n";
for(i=0;i<100;i++)
fout<<a[i].name<<" "<<a[i].height<<endl;
fout.close();
ifstream fin("stu.txt");
if(!fin)
cout<<"文件打开失败\n";

for(i=0;i<100;i++)

fin.close ();
stu *head,*p,*temp;

重载>>，以接收参数为student *

[Chivalry]

while(fin>>b[i].name>>b[i].height>>(char*)b[i].next) 
i++; 

[xajnewuser]

while(fin>>b[i].name>>b[i].height>>b[i].next)
没调试出来，暂时还不知怎么修改
