Question

Is it appropriate to call dynamic multidimesional array, an array of arrays?

int **mp = 0;

// Create an array of pointers
mp = new int*[6];

// Where each element of type pointer, points to dynamic array.
for (int x = 0; x < 6; x++)
    mp[x] = new int[7];

Looking at this, I would say they are array of pointers pointing to arrays of size 7 ints.
But are dynamic arrays even considered arrays or just a chuck of memory returned by pointer?

Answer 1

If I understand correctly, your question is about semantics. As far as the standard is concerned, new [] does create an array, but returns a pointer to the first element. From 5.3.4/5 of the standard:

When the allocated object is an array
… the new-expression yields a
pointer to the initial element (if
any) of the array.

So in your case, what we colloquially call “an array of arrays” is really an array of pointers, which is distinct from e.g. int x[6][6], which is truly an array of arrays.
