int main(void)
{
    int i[12] = {i[1] = 3600, i[2] = 3600 * 2, i[3] = 3600 * 3, i[4] = 3600 * 4, i[5] = 3600 * 5, i[6] = 3600 * 6, i[7] = 3600 * 7, i[8] = 3600 * 8, i[9] = 3600 * 9, i[10] = 3600 * 10, i[11] = 3600 * 11, i[12] = 3600 * 12};
    int j;
    printf(":");
    scanf("%d", &j);
    system("shutdown -s -t i[j]");
    return 0;
}

重点不是在这里，system("shutdown -s -t (i[j]这里写的对不对) ")

这是数组套数组？
