这就是一个结构体数组的遍历问题，代码如下：
#include <stdio.h>
#define N 5
typedef struct
{
int sno;
char name[32];
double daily;
double middle;
double final;
}Student;
int main(void)
{
int i;
Student stus[N];
for(i=0; i<N; ++i)
{
scanf("%d%s%lf%lf%lf", &stus[i].sno, stus[i].name,
&stus[i].daily, &stus[i].middle, &stus[i].final);
printf("%d,%s,%.2lf
", stus[i].sno, stus[i].name,
stus[i].daily*0.1+stus[i].middle*0.2+stus[i].final*0.7);
}
return 0;
}
