Why is is that when I create my array with this line:

      double b[6] = {1/6, 5/24, 11/120, 19/720, 29/5040, 1/840};

and then cout the contents using:

      for (Counter2 = 0; Counter2 < 6; Counter2++)
            cout << "b[" << Counter2 << "]: " << b[Counter2] << endl;

The resulting output is:

b[0]: 0
b[1]: 0
b[2]: 0
b[3]: 0
b[4]: 0
b[5]: 0

you are dividing integers and resulting integer (0) is then cast to double.
