Description

This PR addresses issue #1293 by adding proper input validation to the Caesar cipher script.

Changes Made

  1. Empty message validation — The script now rejects empty message inputs with a clear error message instead of silently producing an empty result.
  2. Non-alphabetic character warning — Users are now warned how many non-alphabetic characters will be left unchanged during encryption/decryption.
  3. Improved error messages — Clear, user-friendly feedback for all validation failures.
