Credit card validation Problem. A credit card number must be between 13 and 16 digits. It must start with:
–4 for visa cards
–5 for mater cards
–37 for American express cards
–6 for discover cards
•Consider a credit card number 4380556218442727
•Step1: double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number.
•Step2: now add all the single digit numbers from step1
4 + 4 + 8 + 2 + 3 + 1 + 7 + 8
•Step3: add all digits in the odd places from right to left in the card number
7+ 7 + 4 + 8 + 2 + 5 + 0 + 3 = 36
•Step4: sum the results from step 2 and step 3
37 + 36 = 73
•Step 5: if the results from step 4 is divisible by 10, the card number is valid; otherwise, it is invalid. In this case, the card number is not valid – because 75 not divisible by 10. use modulus operator
Use these numbers to help test your code. Hint, these examples do not test all possibilities!
