Output a shape that is a mirror image of itself , BUT, only 3 loops allowed

[juniorjames]

So we can't just do the top half of the shape, then do another bunch of loops as the opposite to output the second half of the shape. This is what i did, but i'm told it can be done in no more than 3 loops. I can't quite figure out how though and i'm intrigued!

This is how it should look:

  *********
    *******
      *****
        ***
          *
        ***
      *****
    *******
   *********



    void draw3c()
{
    for (int i = 0; i <= 4; i++ )
    {
        for (int j = 0; j < i; j++)
            cout << " ";
        for (int s = 0; s < 9 - (i * 2); s++)
            cout << "*";
        for (int j = 0; j < i; j++)
            cout << " ";
        cout << "\n";
    }
    for (int i = 0; i < 4; i++)
    {
        for (int j = 0; j < 3 - i; j++)
            cout << " ";
        for (int s = 0; s < 3 + (i * 2); s++)
            cout << "*";
        for (int j = 0; j < 3 - i; j++)
            cout << " ";
        cout << "\n";
    }
    }
