试编写一个程序完成：有5个学生，每个学生的数据包括学号、姓名、3门课的成绩，从键盘输入5个学生数据，要

#include<stdio.h>
#define N 5

struct student
{char num[6];
char name[8];
float score[3];
float avr;
}stu[N];

int main()
{int i,j,maxi;
float sum,max,average;

for(i=0;i<N;i++)
{
printf("input scores of student %d:\n",i+1);
printf("NO.:");
scanf("%s",stu[i].num);
printf("name:");
scanf("%s",stu[i].name);

for(j=0;j<3;j++)
{
printf("score %d:",j+1);
scanf("%f",&stu[i].score[j]);
}
}

average=0;
max=0;
maxi=0;
for(i=0;i<N;i++)
{
sum=0;
for(j=0;j<3;j++)
sum+=stu[i].score[j];
stu[i].avr=sum/3.0;
average=average+stu[i].avr;
if(sum>max)
{
max=sum;
maxi=i;
}
}

average/=N;

printf("NO. name score1 score2 score3 average\n");
for(i=0;i<N;i++)
{
printf("%5s%10s",stu[i].num,stu[i].name);
for(j=0;j<3;j++)
printf("%9.2f",stu[i].score[j]);
printf("%8.2f\n",stu[i].avr);

}
printf("average=%5.2f\n",average);
printf("最高分:学生 %s,%s\n",stu[maxi].num,stu[maxi].name);
printf("成绩：%6.2f,%6.2f,%6.2f,average:%5.2f.\n",stu[maxi],score[0],stu[maxi].score[1],stu[maxi].score[2],stu[maxi].avr);
return 0;
}
