我想使用std :: forward_list模板将我的cardpointers存储在其中但是有一些我无法解决的问题。
错误：
error C3867: 'std::forward_list<Card *,std::allocator<_Ty>>::pop_front': function call missing argument list; use '&std::forward_list<Card *,std::allocator<_Ty>>::pop_front' to create a pointer to member

如果你能解决我的问题，那将是非常好的
答案 0 :(得分：2)
你在函数调用中缺少一些（）：
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###
}
