Hello,course is continues...In this tutorial you will learn how to use "datetime" variable.Why is this important? It is important because you can use this variable to calculate every time period.This program will ask user their birth date,then it will calculate the number of days that user lived.

First of all we define our library as usual.


using System;
using System.Collections.Generic;
using System.Text;


Then we will define our integers which are year,month and day.


int year, month, day;


After defining our integers,we write our title for visuality.


Console.WriteLine("How many days you have lived for until today...\n--------------");


Then we ask users birth date in year,month and day to calculate.Then convert each our integers to 32 byte.


Console.Write("year : ");
year = Convert.ToInt32(Console.ReadLine());
Console.Write("month :");
month = Convert.ToInt32(Console.ReadLine());
Console.Write("day :");
day = Convert.ToInt32(Console.ReadLine());


Then we will build a class for users input and equalize it to new class.This is where we use datetime method."datetime" will take todays date from database.


DateTime Birthdate = new DateTime(year, month, day);


This part is important.Every four years theres a day adding this line is to find out how many four years has passed.


int extraday = (DateTime.Today.Year - Birthdate.Year) / 4;


Now in this part first of all we asked users birthdate by year,month and day.First we multiply users year of birth to 365.Here comes another variable which is very useful; "Dayofyear" this feature is used for to calculate users year of birth year to this year.In the final step we sum up result to the extaday and we get the result.Finally we tell how many day that user has lived until today.


int result = (DateTime.Today.Year - Birthdate.Year) * 365 + (DateTime.Today.DayOfYear - Birthdate.Year) + extraday;
Console.WriteLine(result + " day you have lived until today... ");
Console.Read();


Output of the program;
