How to describe a pointer to a two-dimensional array?

Question

C++ / C#

Good evening
Of course I understand, the question may be a bit stupid, but I can't use ii in my program in any way. How can this object be used to iterate over all the elements of a two-dimensional array?

int i[2][2] = {{1, 2}, {3, 4}};
    int **ii = (int**)i;

Answer 1

int i[2][2] = {{1, 2}, {3, 4}};
int (*ii)[2] = i;
ii[0][0];
