自己写的一段代码，编译正常，运行出错……求解……
#include<iostream>
#include<string>
using namespace std;
struct student
{
short unsigned int num;
string name;
float score[3];
student *next;
};
void creat(void)
{
int i,s;
cout<<"请输入学生总数：";
cin>>s;
student *p;
cout<<"现在开始按学号顺序建立学生档案"<<endl<<endl;
for(i=1;i<=s;i++)
{
cout<<"现在输入"<<i<<"号学生姓名：";
cin>>p->name;
(p->next)=new student;
p=p->next;
}
}
int main(void)
{
creat();
return 1;
}
p=new student;
cin>>p->name;
p=p->next;
