Write a program that performs Credit Card Number Check. Your program should (Note that the blue part represents the user input, and "4" represents the return key from
repeatedly ask the user to input an 8-digit number to check if it is valid, until the user
enters -1 to quit. (Please note that for simplicity, now you can assume the user will
always enter 8-digit numbers to check except for quitting the program with -1. In the
coming week, we will learn how to handle the user input validation). Please note that this
Lab assignment is from the Programming Project 4.22.21 of the ZyBook.
Your program will implement the following algorithm:
The last digit of a credit card number is the check digit, which protects against
transactions errors such as an error in a single digit or switching two digits. The following
method is for numbers with 8 digits:
Starting from the rightmost digit, form the sum of every other digit. For example,
if the credit card number is 43589795. Then you form the sum 5+7+8+
3=23
Double each of the digits, which were not included in the preceding step. Add all
digits of the resulting numbers. For example, with the number given above,
doubling the digits, starting with the next-to-last one, yields 18,18,10,8.
Adding all digits in these values yields 1+8+1+8+1+0+8=
Add the sums of the two preceding steps. If the last digit of the result is 0, the
number is valid. In our case, 23+27=50, so the number is valid.
After the user supplies an 8-digit number, your program should implement the above
algorithm, then print out whether the number is a valid credit card number or not. If it is
not valid, you should print out the value of the check digit that would make the number
valid.
The following show some examples of running your program:
