Introduction Validation codes are often used to reduce errors that may be caused by incorrect data entry, scanning errors or simple attempts at fraud. Various codes are used to validate ISBN numbers, UPC codes, postal money order serial numbers, credit card codes, etc. In this assignment we will implement the algorithm used to verify Canadian Social Insurance Numbers. Social Insurance Numbers (SINs) are validated using a simple check digit process known as the Luhn Algorithm described below Assignment Write a C program that reads a sequence of nine digit numbers from a file and outputs each number with a message indicating whether it is or is not a valid SIN. You can use a negative number at the end of the file to signal the Introduction Validation codes are often used to reduce errors that may be caused by incorrect data entry, scanning errors or simple attempts at fraud.
