Answer 1

供参考：

#include<stdio.h>
#define N 11
int main()
{
    int n, count = 0, a[N], sum = 0;
    double aver;
    scanf("%d", &n);
    if (n <= 0 || n > 10) {
        printf("lnvalid");
        return -1;
    }
    for (int i = 0; i < n; i++){
        scanf("%d", &a[i]);
        sum += a[i];
    }
    aver = (double)sum / n;
    printf("%.2f\n", aver);
    for (int i = 0; i < n; i++)
    {
        if (a[i] > aver)
            printf(count++ == 0 ? "%d" : " %d", a[i]);
    }
    if (!count)
        printf(" ");
    return 0;
}
