Could you please elaborate? Could you please post the relevant code?
Usually the caller provides the required array while the called function fills it.

Are you planning on allocating the array dynamically (as in you don't know the dimensions of the array/matrix)? If so, it starts to get more difficult since its hard to conserve the dimensions while passing pointers (still doable, but harder).

Suppose int nArr[][] is 2d array then try this
return nArr;

Solution 1

You can return the start address for the array. For 2D it will be pointer to pointer.
Example a[][] is equivalent to **a.
