function that reads a char array

Hi Experts,

I thought I knew this, but I am getting confused now.  I need to return an array of strings to a caller.
How can I do it.  The following code works, but the caller has to know the size.  If I want the function to return any number of items, how can I do it. ( can you please provide example both using strings and char *)
Thanks.

void getArray(char* a[])
{
	a[0] = "one";
	a[1] = "two";
	a[2] = "three";
	a[3] = "four";
        a[4] = "five";
}

int main() 
{
	char * arr[5];

	getArray(arr);

	for( int  i = 0; i < 5; i++ )
	{
		cout << arr[i] << endl;
	}
	getchar();
}
