<>使用结构体输出学生成绩
例：输入学生成绩和信息，然后输出最高分学生信息。
#include<stdio.h> struct student { int number; char name[20]; float score[3];
float sum; }s[3]; int main() { int i,k; float max=0; printf("请输入学生: 学号 姓名 分数1
分数2 分数3\n"); for(i=0;i<3;i++) { printf("%d ",i); scanf("%d %s %f %f %f",&s[i].
number,&s[i].name,&s[i].score[0], &s[i].score[1],&s[i].score[2]); s[i].sum=s[i].
score[0]+s[i].score[1]+s[i].score[2]; printf("sum=%f\n",s[i].sum); if(max<s[i].
sum) { max=s[i].sum ; k=i; } } printf("总分最高的学生姓名是：%s 总分：%f\n",s[k].name,s[k].sum
); }
运行结果：
请输入学生: 学号 姓名 分数1 分数2 分数3 0 58 liu 99 98 97 //输入内容 sum=294.000000 1 59 he 99 98
100 //输入内容 sum=297.000000 2 60 chang 95 96 91 //输入内容 sum=282.000000
总分最高的学生姓名是：he 总分：297.000000 -------------------------------- Process exited
