You cannot return arrays from functions. What exactly do you want to do?
Some alternatives are passing in a pointer to the beginning of the array and
filling it within the function or using std::vector instead of a raw array.

The closest approximation to what you ask for that I know of is to wrap the
array in a structure and return the structure. I suspect the cure is worse
than the disease. You might want to re-think what you are trying to do. In
the code I point at a global variable for test purposes. After all, a
pointer serves no purpose without a pointee. I would think in terms of the
caller setting up an array, perhaps empty, and passing a reference to that
array to the function.

int k = 1024;

struct S
{
int* ip[20];
};
//---------------
S foo()
{
S s;
s.ip[16] = &k;
return s;
}
//===============
int main()
{
S t;
t = foo();
cout << *(t.ip[16]) << endl;
}
