这是一个打分程序，n个评委评分，去掉最高分，最低分，然后求平均分。  
 我自己写了一个，运行结果不对，求各位高手指点


#include<stdio.h>
void main()
{
    int a[100],n,i,total,max,min,grade;
    scanf("%d",&n);
    printf("there are %d judges\n",n);
    if(n<=2)
        printf("data error\n");
    else
        printf("please input grades\n");
    for(i=1,total=0;i<=n;i++)
    {
        scanf("%d",&a[i]);
        printf("number %d judge give %d scores\n",i,a[i]);
        total=total+a[i];
    }
    max=a[1];
    for(i=1;i<=n;i++)
    {
        if(max<a[i+1])
        max=a[i+1];
    }
    printf("the highest grade is %d\n",max);
    min=a[1];
    for(i=1;i<=n;i++)
    {
        if(min>a[i+1])
        min=a[i+1];
    }
    printf("the lowest grade is %d\n",min);
    grade=(total-max-min)/(n-2);
    printf("the final grade is %d\n",grade);
}

谢谢了，运行结果是对的。
