Question

a program that will tell which generation a user belongs to first asks the user to input their date of birth. what kind of data validation would be best to use? (1 point) has the user inputted a date in the past? has the user verified their password? is the month a number between 1 and 12? does the year match the month?

Explanation:

• Option 1: A date of birth must be in the past. This is a fundamental check for a valid date of birth.
• Option 2: Password verification is unrelated to validating a date of birth.
• Option 3: While checking if the month is between 1 - 12 is part of date validation, it's not the most comprehensive check for a date of birth (e.g., a future date with a valid month is still invalid for DOB).
• Option 4: Checking if the year matches the month (e.g., February 30th in a non - leap year) is a date - formatting check, but a date in the future with correct formatting is still invalid for DOB.

Answer:

Has the user inputted a date in the past?
