C++ Error 38：关于STD:：转发文件成员引用错误 对于学校，我们必须在C++中创建游戏专卖，但在我的游戏中遇到了问题。

我想使用std：：forward_list模板在其中存储我的cardpointers，但有一些问题我无法解决

错误：

我的甲板头

最后，我的cpp代码本身在有错误的行中添加了额外的注释

---

如果你能帮我解决我的问题，那就太好了

你只是缺少了一些函数调用：

void Deck::shuffle()
{
    std::forward_list<Card*> help;
    help.swap(m_deck);

    while (!help.empty())
    {
        if (rand() % 2 == 0)
        {
            m_deck.emplace_front(help.front());
            help.pop_front(); //###line 65###
        }
        else
        {
            m_deck.emplace_after(m_deck.end(), help.front()); //###line 69###
            help.pop_front(); //###line 70###
        }
    }
}

Card* Deck::takeFront()
{
    Card* help = m_deck.front();
    m_deck.pop_front(); //###line 78###
    return help;
}

void Deck::placeBack(Card* card)
{
    m_deck.emplace_after(m_deck.end(), card); //###line 84###
}

你需要帮助。pop_front，而不是help。pop_front.和m_deck.end，而不是m_deck.end
