c++ - 如何检查number1，number2和number3是否等于a，b和c，但不一定按此顺序

Question

我有一个生成三个随机数的游戏，您必须猜测它们。我不知道如何检查这3个数字是否与生成的数字相同。我已经写了这个，但是我知道它确实很糟糕并且不可读。我在寻找更好的东西，但没有找到任何东西。有什么方法可以使其变得更好和更易读？

bool Guess(int number1, int number2, int number3)
{
    int guess1, guess2, guess3;

    std::cout << "Enter three numbers separated by spaces: ";

    std::cin >> guess1 >> guess2 >> guess3;

    if (guess1 == number1)
    {
        if (guess2 == number2)
        {
            if (guess3 == number3)
            {
                return true;
            }
            else
            {
                return false;
            }
        }
        else if (guess2 == number3)
        {
            if (guess3 == number2)
            {
                return true;
            }
            else
            {
                return false;
            }
        }
        else
        {
            return false;
        }
    }
    else if (guess2 == number1)
    {
        if (guess1 == number2)
        {
            if (guess3 == number3)
            {
                return true;
            }
            else
            {
                return false;
            }
        }
        else if (guess1 == number3)
        {
            if (guess3 == number2)
            {
                return true;
            }
            else
            {
                return false;
            }
        }
        else
        {
            return false;
        }
    }
    else if (guess3 == number1)
    {
        if (guess2 == number2)
        {
            if (guess1 == number3)
            {
                return true;
            }
            else
            {
                return false;
            }
        }
        else if(guess1 == number2)
        {
            if (guess2 == number3)
            {
                return true;
            }
            else
            {
                return false;
            }

        }
        else
        {
            return false;
        }
    }
    else
    {
        return false;
    }

}

这是我如何生成这些数字的片段

int GenerateNumber(int level)
{
    if (level == 1)
    {
        return (rand() % 2) + level; // if level is one than number range is from 1 to 2
    }
    else
    {
        return (rand() % level) + level; // else number range is from level to (level * 2) - 1
    }
}

int a = GenerateNumber(level);
int b = GenerateNumber(level);
int c = GenerateNumber(level);

如果顺序无关紧要，则将顺序更改为易于执行的顺序。为此，您可以将猜测和数字放在单独的数组中，对它们进行排序，然后进行比较。通过使用 std::multiset / std::unordered_multiset 为您完成所有这些工作，您可以使整个过程更加容易。看起来像

bool Guess(int number1, int number2, int number3)
{
    int guess1, guess2, guess3;

    std::cout << "Enter three numbers separated by spaces: ";

    std::cin >> guess1 >> guess2 >> guess3;

    return std::multiset<int>{guess1, guess2, guess3} == std::multiset<int>{number1, number2, number3};
}
