一段VC代码,不知道怎么运行不了

# include"stdio.h"
# define NULL 0
struct student
{
long num:
float score;
struct student *next;
};
void main()
{
struct student a,b,c,*head,*p;
a.num=10101;a.score=89.5;
b.num=10103;b.score=90;
c.num=10107;c.score=85;
head =&a;
a.next=&b;
b.next=&c;
c.next=NULL;
p=head;
do
{printf("%ld%5.1f\n",p->num,p->score);
p=p->next;
}while(p!=NULL);
}
总是提示没有定义变量,明明定义了啊
