1.Based on your own programming experience, suggest three examples of code smells, apart from those listed in Table 8.6 0, that might suggest the need for program refactoring. 2.

Assuming that credit card numbers are 16 digits long, look up and implement the Luhn algorithm to check that a valid credit card number has been input.
