[SOLVED] It 210 programming assignment 1

Make your output look just like this. I will check with other 8-digit numbers. The output below is from
two runs. DO NOT loop to do multiple 8-digit numbers in a single run. It is possible to do this assignment
without using loops at all, however, your solution MUST use loops to calculate the sums.
Enter an 8-digit credit card number: 12345678
The number is not valid. The check digit should be: 4
Enter an 8-digit credit card number: 12345674
That number is valid.
