![]() ![]() ![]() IN NO EVENT WILL THE AUTHOR BE LIABLE FOR ANY DAMAGES RESULTING FROM THE USE OF THIS SOFTWARE. THIS SOFTWARE IS PROVIDED AS IS AND COMES WITH NO WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED. The way it does so is by applying a series of computations to the credit card number given, adding up the results of those. In this task, you must implement a version of Luhn algorithm using the instructions given below. The key thing in this algorithm is to find a check digit, which should be the rightmost digit in any credit card number. ![]() You may distribute and/or use for any purpose modified or unmodified copies of this software. Write a complete C++ program (7 Marks) Some credit card companies use Luhn algorithm to detect invalid credit card numbers. Test credit card account numbers can be found here. The sample "main" C program accepts one or more number strings on the command line.įor an excellent description of the Luhn algorithm refer to the Wikipedia page. Sample C function "check_number()" to check a numeric character string of any length with Luhn check-digit at end of string plus sample C function "calc_digit()" to calculate check-digit character for a given character string. Luhn algorithm (credit card check-digit) implemented in pure C language ![]()
