int *generateRandomArray()
{
    srand((unsigned)time(NULL));
    int length = rand() % maxLength;
    int *arr = new int[length];
    for (int i = 0; i < length; i++)
    {
        arr[i] = rand() % (2 * maxSize) - maxSize;
    }
    return arr;
}

如图，我试图这样生成随机数组，可是Debug中发现For循环里无法访问到数组arr，请问我哪里的语法有问题吗
