求出去最高分和最低分的最终得分

#include <stdio.h>

int main()
{
    int i,n;
    double grade,defen,max,min;
    while (scanf_s("%d", &n))
    {
        max = 0;
        min = 100;
        defen = 0;
        for (i = 0; i < n; i++)
        {
            scanf_s("%lf", &grade);
            defen += grade;

            if (max < grade)
                max = grade;
            if (min > grade)
                min = grade;
        }
        defen = (defen - min - max) / (n - 2);
        printf("%.2lf", defen);
    }
    return 0;
}

参考答案

#include <stdio.h>

int main(void)
{
    int n, i;
    double min, max;
    double x, y;
    
    while (scanf("%d", &n) != EOF)
    {
        scanf("%lf", &x);
        min = max = x;
        for (i = 1 ; i < n ; i++)
        {
            scanf("%lf", &y);
            x += y;
            if (y > max) max = y;
            if (y < min) min = y;
        }
        printf("%.2lf
", (x - min - max) / (n - 2));
    }

    return 0;
}
