Return 双端队列 C++

Question

如何在 C++ 中 return 双端队列数组？

private:
   deque<int> iHouses[3];

public:
   deque<int> getHouses();

//当然在实现功能时给我一个错误 - 但是我应该把括号放在哪里？

 deque<int> GameEngine::getHouses() {
    return this->iHouses;
}

Answer 1

只需使用 std::array

#include <array>
    ....
private:
    using my_house_cont = std::array<std::deque<int>, 3>;
    my_house_cont m_houses;

public:
    my_house_cont getHouses();
