Write a program $$File Encryption and Decryption$$

File Encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Your program should be able to decrypt the encrypted file. Your program should output the decrypted contents on a separate file and also on the console.

Although there are complex encryption techniques $($which you will study eventually if you are a CS major$),$ you should come up with simple algorithm of your own.

For example, you could read the first file one character at a time and add $10$ to the ASCII code of each character before it is written to the second file.

Please write separate functions for each part of the algorithm
