C#: Display the number of days of the year between two specified years

C# Sharp DateTime: Exercise-4 with Solution

Write a C# Sharp program to display the number of days of the year between two specified years.

Sample Solution:-

C# Sharp Code:

using System;

public class Example4
{
    // Main method, entry point of the program
    public static void Main()
    {
        // Creating a DateTime object for December 31, 2000
        DateTime dec31 = new DateTime(2000, 12, 31);

        // Loop that adds years to the initial date and displays information for each iteration
        for (int ctr = 0; ctr <= 20; ctr++)
        {
            // Adding 'ctr' years to the initial date (dec31)
            DateTime dateToDisplay = dec31.AddYears(ctr);

            // Displaying information about the current date:
            // - The date itself in short date format {0:d}
            // - The day of the year {1}
            // - The year {2}
            // - Checking if the year is a leap year and adding "(Leap Year)" if true
            Console.WriteLine("{0:d}: day {1} of {2} {3}", dateToDisplay,
                              dateToDisplay.DayOfYear,
                              dateToDisplay.Year,
                              DateTime.IsLeapYear(dateToDisplay.Year) ?
                                                  "(Leap Year)" : "");
        }
    }
}
 

Sample Output:

12/31/2000: day 366 of 2000 (Leap Year)  
12/31/2001: day 365 of 2001
