c++ - 如何使用 'n' 维数组声明 std::vector？

Question

我的想法如下:
例如一个二维数组:

int a[9][9];
std::vector<int** a> b;

但是如果我有呢

/* I know, it is usually a bad practise to have more than 2 dimensional arrays, but it can happen, when you need it */
int a[3][4][5][6]; 
std::vector<int**** a> b; // ? this just looks bad

Answer 1

试试这个:

struct MD_array{ //multidimentional array
   a[3][4][5][6];
};
std::vector<MD_array> b;

然后你可以像这样访问每个数组:

b[i].a[x][y][z][w] = value;
