返回deque数组c++

Question

如何在c++中返回deque数组？

private:
   deque<int> iHouses[3];

public:
   deque<int> getHouses();

//在实现函数时给出了一个错误--但是我应该把括号放在哪里呢？

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

Answer 1

只需使用std：：数组

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

public:
    my_house_cont getHouses();
