Answer 1

To write a program that separates card numbers based on their issuing network types into separate files, you can use a programming language such as Java or Python.

Step-by-step explanation:

To write a program that reads card numbers from a file and separates them according to their issuing network types into separate files, you can use a programming language such as Java or Python. Here's a general outline of how you can approach this:

1. Read the card numbers from the file.
2. For each card number, extract the first few digits to determine the issuer identification number (IIN).
3. Based on the IIN, write the card number to the corresponding file for the issuing network type (e.g., Visa, MasterCard, American Express, Discover).

By following this approach, you can separate the card numbers into different files based on their issuing network types.
