Next, we give a pseudocode to compute the age in years. For the sake of simplicity, we assume that eligibility to vote
is determined on 01 January of the year. We will assume that day.DD, day.MM, and day.YYYY denotes the day,
month, and year for the date day. If a person is eligible to vote, we set eligible as true and false otherwise.
Input: Date of birth—DOB
Process: If the difference between the current year and the year of date of birth is greater than 18, eligible is set
to True.
Output: Eligible—True, Not Eligible—False

today ← Today's date from System

if (today.YYYY - DOB.YYYY) > 18 then
age ← today.YYYY - DOB.YYYY
eligible ← True
else if (today.YYYY - DOB.YYYY) equals 18 then
if DOB.DD equals 1 and DOB.MM equals 1 then

age ← 18
eligible ← True
else

not eligible ← False

Start

today = today's date

False
today.YYYY–DOB.YYYY>18 today.YYYY–DOB.YYYY=18

True True

age = today.YYYY–DOB.YYYY DOB.MM = 1 and DOB.DD = 1 False eligible = False
eligible = True

True

age = 18
eligible = True
