#include "stdio.h"
#define N 100
void main()
{
int a[N],unpass=0;

把100分定为最高分，60分为及格分数线。用C语言实现如下：
#include<stdio.h>
int main()
{
int sum=0,min=1000,jg=0,i,a[100];
for(i=0;i<100;i++)
{
printf("第%d个学生的成绩:",i); //若不需要提示可将此行删除
scanf("%d",&a[i]);
sum+=a[i];
if(a[i]<min)min=a[i];
if(a[i]>=60)jg++;
}
printf("平均分=%.2f\n最低分=%d\n及格率=%d%%\n",sum/100.0,min,jg);
system("pause");
return 0;
}
