for(int i = 0; i < 3; i++)
{
a[i] = new int[3];
}
for(int vertical = 0; vertical < 3; vertical++)
{
for(int horizontal = 0; horizontal < 3; horizontal++)
{
a[vertical][horizontal] = (2+vertical)*(horizontal+3);
cout << a[vertical][horizontal] << endl;
...

That makes *a[3] a new 2d array of ints a[3][3]. Remember to delete a.
For an array created like this:
1 2 3 4 5 6
|
int *a[3];
for(int i = 0; i < 3; i++)
{
a[i] = new int[3];
}
|
Proper deletion would be like this:
1 2 3 4
|
for(int i = 0; i < 3; i++)
{
delete [] a[i];
}
