What is printed when a non-numeric zip code is entered in the provided code snippet?

• A. Please use numeric digits for the zip code
• B. Your zip code is valid
• C. Zip code accepted
• D. Zip code formatted correctly

Answer: (A)

When validating a zip code, the program checks that the input consists only of numeric digits. If a non-numeric character is entered, the validation fails and the code typically outputs a message that instructs the user to correct the input. The message “Please use numeric digits for the zip code” fits this scenario perfectly because it directly tells the user what the expected format is and why their current input is not acceptable. It serves as a clear, actionable prompt to enter only digits, which is what the code requires. The other options would indicate the input is valid or accepted, which wouldn’t be shown when a non-numeric value is entered.
