编写一个Nim游戏

Question

这个程序的想法是玩一个Nim游戏。我们为堆生成一个随机数。计算机被随机设置为smart，它使用算法从堆中取出，或者在正常模式下随机从堆中取出。谁先走也是随机决定的。所以我做了三个更小的函数，在while循环中调用turn序列，这个循环一直持续到堆栈为1。我测试了它的运行，我只得到了显示计算机是否处于智能模式以及它是谁的输出。在我把更多的精力放在这个程序上之前，我需要知道我哪里出错了。为什么它不工作？

编辑:智能模式的算法是2减1的幂，IE2^4=16-1=15，但我不知道如何用pileSize数学地解决这个问题，所以我只使用了很多if语句。

void Nim();
int PlayerTurn(int);
int ComputerTurn(int);
int SmartComputer(int);

int main()
{
    srand(time(NULL));
    Nim();
    return 0;
}

int PlayerTurn(int pileSize)
{
    int userInput = 0;
    bool flag = true;

    while(flag == true)
    {
        cout << "There are " << pileSize << " in the pile" << endl;
        cout << "How many do you want to take? ";
        cin >> userInput;
        if (userInput > 1 && userInput < (pileSize/2))
        {
            pileSize = pileSize - userInput;
            flag = false;
        }
        else
        {
            cout << "Error, that's not a valid move." << endl;
        }
    }
    return pileSize;
}

int ComputerTurn(int pileSize)
{
    cout << "The computer will take from the pile. " << endl;
    pileSize = pileSize - rand() % (pileSize/2);
    return pileSize;
}

int SmartComputer(int pileSize)
{
    cout << "The computer will take from the pile. " << endl;
    if (pileSize>63)
    {
        pileSize = 63;
    }
    else if (pileSize>31&&pileSize<63)
    {
        pileSize = 31;
    }
    else if (pileSize>15&&pileSize<31)
    {
        pileSize = 15;
    }
    else if (pileSize>7&&pileSize<15)
    {
        pileSize = 7;
    }
    else if (pileSize>3&&pileSize<7)
    {
        pileSize = 3;
    }
    else
    {
        pileSize = pileSize - rand() % (pileSize/2);
    }
    return pileSize;
}

void Nim()
{
    int pileSize = rand()% (100-10) + 10;
    bool smartOrStupid = rand() % 2;
    if (smartOrStupid == true)
    {
        cout << "The computer is in smart mode." << endl;
    }

    bool turn = rand() % 2;
    if (turn = true)
    {
        cout << "The computer will got first. " << endl;
    }
    else
    {
        cout << "The player will go first. " << endl;
    }
    while(pileSize!=1);
    {
        if (turn = true)
        {
            if (smartOrStupid = true)
            {
                pileSize = SmartComputer(pileSize);
                cout << pileSize;
            }
            else
            {
                pileSize = ComputerTurn(pileSize);
                cout << pileSize;
            }
        }
        else
        {
            pileSize = PlayerTurn(pileSize);
            cout << pileSize;
        }
    }
}

Answer 1

问题是这里的分号是while(pileSize != 1);

它创建了一个无限循环。
