Question

以下是两个功能：一个用于掷骰子，另一个用于滚动统计数据。当你掷骰子时，它每次给你一个随机值，这是好的。但是当滚动一个stat时，它似乎给了我所有6次迭代的相同随机值。我想这可能是因为在每次迭代后它没有正确地重置resultStat。

以下是代码：

int Roll_Dice(int number_of_dice, int number_of_faces)
{
    int i;
    int result = 0;

    srand((unsigned) time(NULL));

    for (i = 0; i < number_of_dice; i++)
    {
        result = (rand () % number_of_faces) + 1;
    }
    return (result);
}

int Roll_Stat(int number_of_dice, int use_highest)
{
    int i, a, b;
    int numberRolled[number_of_dice];
    int resultStat = 0;

    for (i = 0; i < number_of_dice; i++)
    {
        numberRolled[i] = Roll_Dice(number_of_dice, 6);
    }
    for (a = i + 1; a < number_of_dice; a++)
    {
        if (numberRolled[i] > numberRolled[a])
        {
            b               = numberRolled[i];
            numberRolled[i] = numberRolled[a];
            numberRolled[a] = b;
        }
    }
    for (i = use_highest; i >= (number_of_dice - use_highest); i--)
    {
        resultStat += numberRolled[i];
    }

    return (resultStat);
}

Answer 1

由于rand只有第二个粒度，因此每次再次在同一秒内再次调用time并重新播种Roll_Dice时，rand只会有第二个粒度。

您需要在Roll_Dice之外播种随机数生成器，然后只需对其中的String[] command = { "ssh", "hddev-chost-01-01", "\"" + element + "\"" };进行连续调用。正如您目前所做的那样，每次都使用相同的参数调用String element = "sqoop import -D oraoop.disabled=true -D

}，并且每次都将随机数生成器初始化为相同的内容（除非您在计算过程中碰巧越过第二个边界，这不太可能它应该很快），所以结果应该是一样的。
