请教一下大家

struct Srudent  //student

LZ犯了很多小错误，以后应该注意下

修改如下：

# include <stdio.h>
# include <malloc.h>
# define LEN sizeof(struct Student)

struct Student// 不是Srudent
{
	long num;
	float score;
	struct Student *next;
};

int n;

struct Student * creat()
{
	struct Student * head;//Studnet 中的S要大写
	struct Student *p1, *p2;
	n = 0;
	p1=p2=( struct Student * )malloc(LEN);
	 scanf("%ld, %f", &p1->num, &p1->score);//scanf
	head=NULL;
	while(p1 -> num!=0)
	{
  
		n=n+1;
		if(n==1)
		head=p1;
		else
		p2->next=p1;
		p2=p1;
		p1=(struct Student * )malloc(LEN);
		scanf("%ld, %f", &p1->num, &p1->score);

	}
	p2->next=NULL;
	return(head);

}

void prin(struct Student *head) //此处head应该为指针
{
    struct Student *p;
    printf("\nNow,These %d records are:\n", n);// printf
    p=head;
    if(head!=NULL)// !=只有一个=
	do  //代码块应用{} 
	{
	    printf("%ld %5.1f\n",p->num,p->score);
		p=p->next;
	} while(p!=NULL);
}
void main()
{
    struct Student *head;
    head=creat();
    prin(head);
}
