An array of two-dimensional arrays?

Question

C++ / C#

How to create an array of two dimensional arrays?

int a0[2][2] = { {1,0}, { 0,1}};
int a1[2][2] = { {1,1}, {0,0}};
//??? не работает
int[2][2] ar[] = {a0, a1};

Answer 1

int a0[2][2] = { {-1,0}, {0,0} };
int a1[2][2] = { {1,1}, {0,0} };
int (*ar[2])[2] = { a0, a1 };

Answer 2

This is already a three-dimensional array.

int arr[2][2][2] = {{ {1, 2}, {1, 2} }, { {1, 2}, {1, 2} } };
