What value does a pointer to pointer get assigned when points to a dynamically allocated memory?

Question

Consider the following case:

int **my_array = new int*[10];

1. What do we assign to my_array here?
2. my_array is a pointer that points to what?
3. Is there any way to iterate through my_array (the pointer) and set up a two-dimensional array of integers (and not int*)?

Answer 1

We assign to my_array the address of an array. The array contains pointers which can point to other arrays, but don't yet.

Yes, we can do this:

int **my_array = new int*[10];

for(int i=0; i<10; ++i)
  my_array[i] = new int[13];

my_array[2][11] = 500;
