代码如下：
#include<stdio.h>
#include<stdlib.h>
#define LEN sizeof(struct Student)
struct Student
{
     char name[10];
    float sorce;
    struct Student *next;
};
struct Student *Creat()
{
    int n,i;
    struct Sutdent *p1=NULL;
        struct Sutdent *p2=NULL;
        struct Sutdent *head;
    head=(struct Student *)malloc(sizeof(struct Student));
    //head->next=NULL;
    p1=head;
    if(head=NULL)
    {
        printf("创建失败\n");
            return NULL;
    }
//    else
//    {
       printf("请问有几个学生？/n");
           scanf("%d",&n);
    for(i=0;i<n;i++)
    {
        p2=(struct Student *)malloc(sizeof(struct Student));
        printf("请输入学生的名字和成绩/n");
        scanf("%s %f",&(p2->name),&(p2->sorce));
        p2=p2->next;
        p2=p1;
    }

}
出现以下错误：error C2037: left of 'name' specifies undefined struct/union 'Sutdent'
              error C2037: left of 'sorce' specifies undefined struct/union 'Sutdent'

Sutdent
Student
p2->name 已经是指针了

还是不太懂

#include<stdio.h>
#include<stdlib.h>
#define LEN sizeof(struct Student)
struct Student
{
     char name[10];
    float sorce;
    struct Student *next;
}*head,*p1,*p2;
struct Student *Creat()
{
    int n,i;
    /*struct Sutdent *p1=NULL;
        struct Sutdent *p2=NULL;
        struct Sutdent * head;*/
    head=(struct Student *)malloc(sizeof(struct Student));
    //head->next=NULL;
    p1=head;
    if(head=NULL)
    {
        printf("创建失败\n");
            return NULL;
    }
//    else
//    {
       printf("请问有几个学生？/n");
           scanf("%d",&n);
    for(i=0;i<n;i++)
    {
        p2=(struct Student *)malloc(sizeof(struct Student));
        printf("请输入学生的名字和成绩/n");
        scanf("%s %f",&(p2->name),&(p2->sorce));
        p2=p2->next;
        p2=p1;
    }

}

把几个指针拿到外面结构体定义
