C++ Small Straight(如 yahtzee 或 poker)。 5 掷骰子 (1234)/(2345)/(3456)

Question

我是 C++ 的初学者，这是家庭作业，但我卡住了。我还有一个问题，然后我就完成了。我想不出一种算法可以判断用户输入的是小直线 (1234) 还是 (2345) 还是 (3456)。我知道如何使用循环来做到这一点，但是否可以不使用循环？分配这个时，我们还没有了解循环。我认为我们只应该使用 if 语句。我开始为它编码(我写了骰子可以是什么，但无法弄清楚如何让 4 个骰子在没有数组和循环的情况下直接运行)。我卡住了!请帮忙!您能否也检查一下我的代码，看看到目前为止是否有任何问题。

分配的问题:

用骰子玩扑克。 (有点像 Yahtzee)

• 让用户以任意顺序输入 5 个骰子 (1-6)。让用户输入 5 个数字。如果有超出 1 到 6 的范围，则结束程序。

• 计算并打印输入的个数。

• 计算并打印输入的二元数。

• 计算并打印输入的三分球​​数。

• 计算并打印输入的四人组数。

• 计算并打印输入的五的数量。

• 计算并打印输入的 6 的个数。

• 判断是否有三个或更多的骰子相同。

• 判断是否有四个或更多的骰子相同。

• 判断是否有五个骰子相同。

• 判断是否有满屋，3 个相同，2 个相同。

• 判断是否有一条长直道... 1 2 3 4 5 或 2 3 4 5 6

• 判断是否有小顺子 (1 2 3 4) 或 (2 3 4 5) 或 (3 4 5 6)

int bits = (1 << Roll1) | (1 << Roll2) | (1 << Roll3) | (1 << Roll4) | (1 << Roll5);
if((bits & 0x1E) == 0x1E || (bits & 0x3C) == 0x3C || (bits & 0x78) == 0x78)
    cout << "Yes Small Straight!" << endl;
