数据结构的例题发现有几个变量名有错（翻译时翻错的）

C Run-Time Error R6002
floating-point support not loaded

The program needs the floating-point library, but the library was not linked to the program.

One of the following may have occurred:

The program was compiled or linked with an option (such as /FPi87) that required a coprocessor, but the program was run on a machine that did not have a coprocessor installed.


A format string for a printf or scanf function contained a floating-point format specification, and the program did not contain any floating-point values or variables.


The compiler minimizes a program's size by loading floating-point support only when necessary. The compiler cannot detect floating-point format specifications in format strings, so it does not load the necessary floating-point routines.


Use a floating-point argument to correspond to the floating-point format specification, or perform a floating-point assignment elsewhere in the program. This causes floating-point support to be loaded.


In a mixed-language program, a C library was specified before a FORTRAN library when the program was linked. Relink and specify the C library last.

#include "stdio.h"
#include "malloc.h"
#define NULL 0
#define LEN sizeof(struct student)

struct student
{   int num;
    float score;
    struct student *next;
};

int n;

struct student *creat()         //把creat()中的void去掉，如左
{   struct student *head,*p1,*p2;
    n=0;
    p1=p2=(struct student *)malloc(LEN);
    printf("input p1.num,p1.score");
    scanf("%d,%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("%d,%f",&p1->num,&p1->score);
    }
    p2->next=NULL;
    return(head);
}
   


   
   
   
   
   
main()                        //把main()函数体改为如左所示
{struct strdent *head;
  head=creat();
   
   
}

也可以到较大型书店买，只是比较金一点，定价60元。

怎么还没高手解释啊，是老谭的书，只介绍了怎么创建函数，没把函数运用到main中，所以不会，我的哪错了，我不要程序，只是想知道我的哪错了

scanf("%d,%f",&p1->num,&p1->score);出错
我看了一下，是&p1->score有问题，原因我也不太清楚，我的办法是前面定义float f;
再scanf("%d,%f",&p1->num,&f);
p1->score=f;
