. File Decryption Filter

Design a program that decrypts the file produced by the program in Programming Exercise 10. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file.

File Encryption

File encryption is the science of writing the contents of a file in a secret code. For this assignment you will design a program that opens a file and encrypts its contents. Assume the file that you are encrypting contains a list of strings. The program should open the file and read its contents, one string at a time. As the program reads a string from the file, it substitutes each character of the string for an alternate character. It then writes the encoded string out to a second file. When the program is finished, the second file will be a version of the first file, but written in a secret code.
