C语言程序设计第四版（何钦铭、颜晖）第九章结构之输出平均分

【练习9-3】例9-1中,如果要计算的是三门课程的课程平均分,应该如何改写程序?

#include<stdio.h> struct Student{ int num; char name[10]; int computer,english,math; double average; }; int main(){ struct Student stu; int n,i; scanf("%d",&n); for(i=1;i<=n;i++){ scanf("%d%s%d%d%d",&stu.num,stu.name,&stu.computer,&stu.english,&stu.math); stu.average=(stu.computer+stu.english+stu.math)/3.0; printf("The average of %s is %.2f\n",stu.name,stu.average); } return 0; }

输入样例：3
111 amy 100 90 98
222 saroy 93 87 100
333 john 98 83 97

输出结果：The average of amy is 96.00
The average of saroy is 93.33
The average of john is 92.67
