In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly, or whether a credit card is scanned correctly by a scanner. Credit card numbers are generated following this validity check, common...
If the result from Step 4 is divisible by 10, the card number is valid; otherwise, it is invalid. For example, the number 4388576018402626 is invalid, but the number 4388576018410707 is valid. Write a program that prompts the user to enter a credit card number as a long integer. Display ...
Firstly;one algorithm of credit card number validation---LUHN Formula (Mod 10) is introduced; and then its application on the wired and wireless internet is realized.JavaScript and VBScript are used separately with HTML to realize this algorithm on the internet; at the same time, WMLScript is ...
public static long getPrefix(long number, int k) Here are sample runs of the program: (You may also implement this program by reading the input as a string and processing the string to validate the credit card.) Enter a credit card number as a long integer: 4388576018410707 4388576018410707...
