结构体为什么这样报错？？

Question

#include<stdio.h>
  int main()
 {
   double average1,average2,average3=0;
   int sum1=0;
   int sum2=0;
   int sum3=0;
   int i=0;
   int temp=0;
  struct student//定义结构体
  {
     int numble=0;
     char name[10]={'\0'};
     double score[3];
     double sum=0;
  };
  struct student stu[10];
  for(i=0;i<10;i++)//遍历输入
  {
    scanf("%d%s%lf%lf%lf",&stu[i].numble,&stu[i].name,&stu[i].score[0],&stu[i].score[1],&stu[i].score[2]);
    stu[i].sum=stu[i].score[0]+stu[i].score[1]+stu[i].score[2];
    sum1+=stu[i].score[0];
    sum2+=stu[i].score[1];
    sum3+=stu[i].score[3];
  }
  average1=sum1*1.0/10;
  average2=sum2*1.0/10;
  average3=sum3*1.0/10;
    int max=stu[0].sum;
  for(i=0;i<10;i++)
  {
   if(stu[i].sum>max)
   {
       max=stu[i].sum;
   }
   temp=i;
  }
    printf("%lf %lf %lf",average1,average2,average3);
    printf("%d %s %lf %lf %lf",stu[i].numble,stu[i].name,stu[i].score[0],stu[i].score[1],stu[i].score[2]);
 }

不能在结构定义的地方这样子赋初始值
