What can I assume about user input?

• • The message will only contain lowercase letters

  • The shift value will be between -25 and 25

    • Hint: The shift may require you to "wrap around" the alphabet
      
      

Can you be more specific about the user interface?

• • The program should have a welcome message or title

  • Every user input should have a descriptive prompt

  • It should be clear how to quit the program, and there should be a message on exit.

  • Think about spacing between lines and messages
    
    

Does the program need to have multiple files?

• • You must use a main file, as well as a separate header file and cpp file.

  • The project framework on replit will provide this basic layout
