There could be several reasons for receiving a null output in your implementation of Caesar's cipher. Some possible reasons are:
Incorrect input: You may have provided an invalid input to your cipher function which is causing it to return a null output. For example, if you are passing a non-string value or an empty string to your function, it may not be able to encrypt it and return a null output.
Incomplete implementation: Your cipher function may not be fully implemented, or some parts of it might be missing. This could cause the function to stop executing and return a null output. You should check your code to ensure that all the required steps of the encryption process are being executed correctly.
Encoding issues: If your input string contains non-ASCII characters, your cipher function may not be able to encode them properly, resulting in a null output. Ensure that your function can handle all types of characters and encoding schemes.
Syntax errors: Syntax errors in your code, such as incorrect use of variables or missing parentheses, can cause your cipher function to fail and return a null output. Check your code for any syntax errors and fix them accordingly.
Logic errors: Logic errors in your code, such as incorrect use of loops or if statements, can also cause your cipher function to fail and return a null output. Review your code to ensure that it is executing all the necessary steps correctly and in the proper order.
