将txt文件中的数据读入数组中 ，为什么只能读第一行数据啊？

将txt文件中的数据读入数组中

下面是源码

#include <stdio.h>
#include <stdlib.h>

struct gene

    int code;
    float Medium1;
    float ToxA1;
    float ToxB1;

    float Medium2;
    float ToxA2;
    float ToxB2;
    float ToxAB2;
    float ToxoidAB2;
    float Medium3;
    float ToxA3;
    float ToxB3;
    float ToxAB3;
    float ToxoidAB3;
    struct gene *next;
};

struct gene*creat(struct gene *h,FILE*fp);

struct gene*insert(struct gene *h,FILE*fp);

void spnt(struct gene *h);

int main()
{
    struct gene *h=NULL;
    FILE*fp;
    fp=fopen("data1.txt","r");
    creat(h,fp);
    insert(h,fp);
    return 0;
}

void spnt(struct gene *h)
{
    if(h==NULL)
    {
        printf("error!");
        return;
    }
    else
    {
        while(h!=NULL)
        {
            printf("%d %f %f %f %f %f ",h->code,h->Medium1,h->ToxA1,h->ToxB1,h->ToxAB1,h->ToxoidAB1);
            printf("%f %f %f %f %f ",h->Medium2,h->ToxA2,h->ToxB2,h->ToxAB2,h->ToxoidAB2);
            printf("%f %f %f %f %f",h->Medium3,h->ToxA3,h->ToxB3,h->ToxAB3,h->ToxoidAB3);
            h=h->next;
        }
    }
}

struct gene*creat(struct gene*h,FILE*fp)
{
    h=(struct gene*)malloc(sizeof(struct gene));
    fscanf(fp,"%d %f %f %f %f %f",&h->code,&h->Medium1,&h->ToxA1,&h->ToxB1,&h->ToxAB1,&h->ToxoidAB1);

    h->next=NULL;
    spnt(h);
    printf("\n%d",ftell(fp));
    return h;
}

struct gene*insert(struct gene *h,FILE*fp)
{
    struct gene *node=NULL,*end=NULL;
    end=h;
    while(!feof(fp))
    {
        node=(struct gene*)malloc(sizeof(struct gene));
        fscanf(fp,"%d %f %f %f %f %f",&node->code,&node->Medium1,&node->ToxA1,&node->ToxB1,&node->ToxAB1,&node->ToxoidAB1);
