Write a C# Sharp program to find the first day of the next month against a given date.

Sample Solution:-

C# Sharp Code:

using System; // Importing the System namespace

class dttimeex56 // Declaring a class named dttimeex56
{
    static void Main() // Declaring the Main method
    {
        int yr, mn, dt; // Declaring variables for year, month, and day

        Console.Write("\n\n Find the first day of the next month against a given date :\n"); // Displaying a message in the console
        Console.Write("----------------------------------------------------------------\n"); // Displaying a separator line

        // Input prompts for day, month, and year
        Console.Write(" Input the Day : ");
        dt = Convert.ToInt32(Console.ReadLine());
        Console.Write(" Input the Month : ");
        mn = Convert.ToInt32(Console.ReadLine());
        Console.Write(" Input the Year : ");
        yr = Convert.ToInt32(Console.ReadLine());

        DateTime d = new DateTime(yr, mn, dt); // Creating a DateTime object with the provided year, month, and day
        Console.WriteLine(" The formatted Date is : {0}", d.ToString("dd/MM/yyyy")); // Displaying the formatted input date
        Console.WriteLine(" The first day of the next month for the above date is : {0}\n", FirstDayOfNextMonth(d).ToString("dd/MM/yyyy")); // Displaying the first day of the next month for the input date
    }

    // Method to find the first day of the next month given a specific date
    public static DateTime FirstDayOfNextMonth(DateTime dt)
    {
        DateTime ss = new DateTime(dt.Year, dt.Month, 1); // Creating a new DateTime object representing the first day of the input month and year
        return ss.AddMonths(1); // Returning the first day of the next month by adding one month to the first day of the input month
    }
}

Sample Output:

Find the first day of the next month against a given date :                                                  
----------------------------------------------------------------                                              
 Input the Day : 12                                                                                           
 Input the Month : 06                                                                                         
 Input the Year : 2017                                                                                        
 The formatted Date is : 12/06/2017                                                                           
 The first day of the next month for the above date is : 01/07/2017
