Project Description
Background
A shift cipher is a basic way to encrypt messages. Each letter of the alphabet is assigned to another letter of the alphabet based on a shift value.
For example, an encrypted message has a shift value of -2: AMBCFQ
When the message is decrypted, it reads: CODEHS
Your Task
You’ll create a program that encrypts and decrypts a user-entered message by using a shift value to reassign the letters. The full decrypted or encrypted message is then printed to the console. You’ll need to use functions with parameters, user inputs, returns, print to the console, and pass arguments when calling functions.
