How can I calculate someone's age based on a DateTime type birthday?
I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

DateTime
type birthday in C#:C#
This code first creates two
DateTime
objects:today
andbirthday
. Thetoday
object represents the current date and time, and thebirthday
object represents the person's birthday.The code then calculates the person's age by subtracting the
birthday
object from thetoday
object. Theyear
property of theDateTime
object is used to get the year of the date.The code then checks if the
today
object is before thebirthday
object. If it is, then the code subtracts 1 from the age. This is because the person is not yet born on the day before their birthday.Finally, the code prints the person's age to the console.
Here is an explanation of the code:
DateTime.Now
property is used to get the current date and time.new DateTime()
constructor is used to create aDateTime
object with a specific date and time.Year
property is used to get the year of aDateTime
object.-
operator is used to subtract twoDateTime
objects.if
statement is used to check if thetoday
object is before thebirthday
object.Console.WriteLine()
method is used to print a string to the console.
