C语言求数组的第二大数

nt second(int value[],int n)
{
    int first = value[];
    int second = value[];

    int i = ;
    for(i = ;i < n;i++)
    {
        if(value[i] > first)
        {
            second = first;
            first = value[i];
        }
        else if(value[i] < first && value[i] > second)
        {
            second = value[i];
        }
    }
    return second;
}

int main()
{
    int value[];
    printf("数入6个数：\n");
    int i = ;
    for(i = ; i < ;i++)
    {
        scanf("%d",&value[i]);
    }

    printf("第二大数为：%d\n",second(value,));

    return ;
