c++ - オブジェクトの二次元配列を宣言して関数から返す方法

Question

正しい構文を教えてください。これがこれまでのコードです

enum Color {WHITE, BLACK};

struct Square
{
  Square(Color p_color): color_(p_color) {}
  Color color_;
};

//instead of Square *, is there a clear way to express intention that function returns 
//Square[][]
Square[][] initSquare(const int rows, const int cols)
{
    Square board[rows][cols]; //Why does compiler complain that Square does not 
                              //have a default constructor? I am just declaring an 
                              //array of type Square

    for(int row=0;row<rows;row++)
            for(int col=0;col<cols;col++)
            {
                    if(col%2 == 0)
                            board[row][col]= Square(WHITE);
                    else
                            board[row][col] = Square(BLACK);
            }
      return board;
}
