This project implements the Caesar Cipher, a simple encryption technique used in cryptography. Users can encrypt and decrypt messages by shifting the letters of the alphabet.

• Encrypt and decrypt messages using a specified shift value.
• Handles letters not in the alphabet without modification.
• User-friendly console interface for input and output.
• Option to play again after each encryption/decryption attempt.

1. Run the script.
2. Choose whether to encode (encrypt) or decode (decrypt) a message.
3. Enter the message you want to encrypt or decrypt.
4. Specify the shift amount (number of positions each letter will be moved).
5. View the result of the encryption or decryption.
6. Choose to play again or exit.
