程序编译出问题了，请指点

编译时出问题，

#include<iostream.h>
struct student
{
long num;float score;
struct student *next;
;
int k=0;
struct student *creat()
{
struct student *head,*p1,*p2;
head=NULL;
p1=new(student);
p2=p1;
cin>>p1->num>>p1->score;
while(k<=5)
{
n++;
if(k==1)
head=p1;
else
p2->next=p1;
p2=p1;
p1=new(student);
cin>>p1->num>>p1->score;
}
delete(p1);
p2->next=NULL;
reture(head);
}

Compiling...
