先说说错在哪里嘛。。。

想实现什么功能？

#include<stdio.h>
#include<malloc.h>
#include<stdlib.h>
#define LEN sizeof(struct Student)
struct Student
{
    long num;
    float score;
    struct Student * next;
};
int n;


struct Student *head;
struct Student *creat(void)
{

    struct Student * p1, *p2;
    n = 0;
    p1 = p2= (struct Student*) malloc(LEN);
    scanf("%ld %f",&p1->num, &p1->score);
    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 print (struct Student *head)
{
    struct Student *p;
    printf("\nNow,There %d records are:\n",n);
    p=head;
    if(head == NULL){
        printf("Open fail!");
        exit(0);
    }
    do
    {
        printf("%ld \t %.2f\n",p->num, p->score);
        p=p->next;
        
    }while(p != NULL);
}
void main()    
{
   // struct Student * pt;
    head=creat();
    print(head);
}
