类getter函数C++的奇怪输出

所以我有一段飞镖游戏的代码，在我的头文件中：

    class Player
    {
    private:
        string playerName;
        int bullAccuracy;
        int outerAccuracy;
        int singleAccuracy;
    public:
        //getters
        string& getName();
        int& getBullAccuracy();
        int& getSingleAccuracy();
        //setters
        void setName(string& name);
        void setBullAccuracy(int& bull_accuracy);
        void setSingleAccuracy(int& single_accuracy);
    };

然后.cpp文件中对应的getter和setter函数如下所示：

    //getters
    string& Player::getName()
    {
        return playerName;
    }
    unsigned int& Player::getScore()
    {
        return playerScore;
    }
    int& Player::getBullAccuracy()
    {
        return bullAccuracy;
    }
    int& Player::getSingleAccuracy() 
    {
        return singleAccuracy;
    }
//setters
void Player::setName(string& name)
{
    playerName = name;
}
void Player::setBullAccuracy(int& bull_accuracy)
{
    bullAccuracy = bull_accuracy;
}
void Player::setSingleAccuracy(int& single_accuracy)
{
    singleAccuracy = single_accuracy;
}

所有这些非常简单和基本的getter/setter代码用于类数据memebers，对吧？

不过，在main（）函数中，我为我的玩家设置了名称，以及它们的各种精度，然后通过getter显示它们。所有这些都是使用对象向量和迭代器完成的，比如：

vector<Player> player(2);
vector<Player>::iterator modIter;
int bAccuracy, sAccuracy;
string playerName;
cout << "Input the name of the players: " << endl;
for (modIter = player.begin(); modIter != player.end(); modIter++)
{
    cin >> playerName;
    modIter->setName(playerName);
}
cout << "nSet the players' bull accuracy:" << endl;
for (modIter = player.begin(); modIter != player.end(); modIter++)
{
    cout << modIter->getName() << ": ";
    cin >> bAccuracy;
    modIter->setBullAccuracy(bAccuracy);
}
cout << "nSet the players' single hit accuracy: " << endl;
for (modIter = player.begin(); modIter != player.end(); modIter++)
{
    cout << modIter->getName() << ": ";
    cin >> sAccuracy;
    modIter->setBullAccuracy(sAccuracy);
}
//display values to check program working well so far
for (modIter = player.begin(); modIter != player.end(); modIter++)
{
    cout << modIter->getBullAccuracy() << endl;
    cout << modIter->getOuterAccuracy() << endl;
    cout << modIter->getSingleAccuracy() << endl;
}

运行代码后，输入"Joe"answers"Sid"作为名称，分别输入71和73作为公牛准确度，然后输入80作为两名玩家的单次命中准确度，这就是我的控制台输出：

输入玩家名称：

Joe

Sid

设置玩家的公牛精度：

乔：71

Sid:73//这意味着至少名称设置正确

设置玩家的单次命中精度：

乔：80

Sid:80

//这是奇怪的输出

80//这应该是71

-842150451//和这个80

80//这里是73

-842150451//这里又是80

到底发生了什么，因为这是getter和setter的基本和熟悉的用法，我不知道如何自己调试，因为我没有看到这个问题。我的代码中是否有我看不到的东西正在改变结果？
