C++错误:初始化结构实例的向量数组成员

Question

我有一个结构如下:

typedef struct
{
    vector<int[6]> swaps;
    int score;
}State;

我随后即时通讯

State s1;
int s1arr[]={1,2,3,4,5,6};
s1.swaps.push_back(s1arr); //this is line number 164 in the error
s1.score=23;

以下所有内容都是一个巨大的错误.我找不到除了位置之外的任何地方的类似错误(不在堆栈溢出的地方也没有应答).当我推回s1.swaps时会发生错误.如果有人能帮助我找出错误,我将感激不尽

Answer 1

你不应该存储C array在矢量中,它既不可复制,也不可移动,也不可分配.如果可以使用C++ 11,则可以使用std :: array,否则可以使用boost::array.你也可以使用std::vector<std::vector<int> >.

vector<array<int, 6> > swaps;
