// The credit card validation rule deserves a bit more attention. After stripping out garbage
// characters, I took advantage of the fact that all Visa card account numbers begin with a 4,
// all MasterCard accounts begin with a 5, all Discover card accounts begin with a 6, and all
// American Express cards begin with a 3. I got the card type from the drop-down list next to
// the credit card entry text field. If the first character isn't correct based on the type,
// the validateCC() function immediately returns false and the data fails the test.
// In addition, credit ards have a fixed number of digits: Amex accounts all contain 15 digits,
// and Visa, MasterCard, and Discover card accounts all contain 16 digits. Therefore, the
// function improves the validation by checking that the data begins with the correct number
// and is the correct length.
