Credit Card Validator
The Credit Card Validator is a C program designed to validate credit card numbers using the Luhn's algorithm. This console-based application allows users to input credit card numbers and determines whether they are valid according to the algorithm.
Features
-
Luhn's Algorithm: The program employs the Luhn's algorithm, which is a widely used checksum formula to validate a variety of identification numbers, including credit card numbers.
-
Card Type Identification: The validator identifies and classifies credit card types, including American Express (AMEX), MasterCard, and Visa, based on their number patterns and length.
-
User-Friendly Interface: The program provides a clear and straightforward command-line interface that prompts users to input credit card numbers. It then provides instant feedback on the validity of the card and its type.
Getting Started
- Clone the Repository: Start by cloning the repository to your local machine. (bash git clone https://github.com/yourusername/CreditCardValidator.git cd CreditCardValidator)
- Compile and Run: Use a C compiler to compile the program's source code and run the executable. (bash gcc -o validator validator.c -lm ./validator)
- Enter Credit Card Numbers: Follow the on-screen instructions to enter credit card numbers for validation.
