struct 链表问题（求助）
#include<iostream>
using namespace std;
struct student
{
__int64 num;
char sex;
char name[10];
char come_from[20];
struct student *next;//请问下这个跟student *next有何区别？;
};
struct student *head;
student *create()
{
struct student *ps;
struct student *pend;
ps=new student;
scanf("%I64d",&ps->num);
cin>>ps->sex>>ps->name>>ps->come_from;
head=NULL;
pend=ps;
while(strcmp(ps->name,"null")!=0)// 这地方我想设置为有输入时执行，但是我不晓得这样写是否正确，求解
{
if(head==NULL)
{
head=ps;
}
else
{
pend->next=ps;
}
pend=ps;
ps=new student;
scanf("%64d",&ps->num);
cin>>ps->sex>>ps->name>>ps->come_from;
}
pend->next=NULL;
delete ps;
return head;
}
void show1(student *p)
{
while(head)
{
printf("%64d",p->num);
cout<<p->sex<<p->name<<p->come_from<<endl;
head=head->next;
}
}
void main()
{
show1(create());
}
要求输入
20100862150 m zhang fuzou
20100862178 f li shanghai
20100862154 m wu sanming
20100862155 f wang zhejian
20100862170 f chen zhangzhou
并原样输出
本人初学小白，望大神能详解……谢谢
[解决办法]
1.没区别
2.while (ps->name)
