True or false: The validation method below will ensure the phone number entered is 10 characters long.

Question

BlackTom AI · Accepted Answer

Question premise: A simple validation loop checks phone input length against 10. Option 1: True. The loop uses While Length(PhoneNumber) <> 10, which means it will keep asking until the length of the entered value is exactly 10 characters. In that sense, the validation enforces a 10-character length constraint. However, note a caveat: the check only ensures the number has 10 characters; it does not verify that all characters are digits or that the input is a valid phone number format. So while the length requirement is enforced, other validity aspects (digits-only, formatting, etc.) are not guaranteed by this snippet. Option 2: False. If the only check is Length(PhoneNumber) <> 10, the loop will still continue until the length equals 10, which means inputs of length 10 are accepted. The statement would be false only if you interpret the method as guaranteeing a fully valid phone number beyond length, such as digit-only or formatting rules, which the snippet does not address. Since the question focuses solely on the length aspect, the loop does enforce a 10-character length. Summary: the code ensures the entered value has exactly 10 characters by looping until that condition is met, but it does not guarantee that those 10 characters form a valid phone number with digits only or proper formatting.
