Vigenere Encryption Program

In this assignment youll write a program that encrypts the alphabetic letters in a file using the Vignere cipher. Your program will take two command line parameters containing the names of the file storing the encryption key and the file to be encrypted. The program must generate output to the console (terminal) screen as specified below is defined in detail here: pa1.pdf

Please note there are 5 key files, respectively named k0.txt thru k4.txt. There are also 5 plaintext files named p0.txt thru p4.txt. And when you unpack the ZIP you'll also see the 5 base case outputs used to check your program's outputs. The base cases are the standard solution for the five respective key and plaintext files.

The test files and script are in the ZIP
