求解，为什么min和max的值都不是我想要的？

#include<stdio.h>
int main()
{
    double score[7], sum, max, min;
    int a = 0;
    for (sum = 0; a < 7; a++)
    {
        scanf("%lf", &score[a]);
        sum += score[a];
    }
    max = score[0],min = score[0];
    for ( a = 1; a < 7; a++);
    {
        if (score[a] > max)
            max = score[a];
        if (score[a] < min)
            min = score[a];
    }
    printf("max = %f,min = %f\n", max, min);
    sum = sum - max - min;
    printf("%f", sum / 5.0);
    return 0;
}

Answer 1

for ( a = 1; a < 7; a++);这一行多了一个分号
