Question

如何在构造函数中轻松初始化数组？例如

class A 
{ 
    array<array<int, 2>, 2> m; 
    A(int m00, int m01, int m10, int m11) 
     : m {m00, m01, m10, m11} // ??? how to list here 
    {} 
}; 

Answer 1

class A 
{ 
    std::array<std::array<int, 2>, 2> m; 
    A(int m00, int m01, int m10, int m11) 
     : m {{{m00, m01}, {m10, m11}}} 
    {} 
};
