Write a program in C# Sharp to read any Month Number in integer and display the number of days for this month.

Sample Solution:-

C# Sharp Code:

using System;  // Importing necessary namespaces

public class exercise23  // Declaration of the exercise23 class
{  
    static void Main(string[] args)  // Main method, entry point of the program
    {
        int monno;  // Declaration of a variable to store the month number

        Console.Write("\n\n");  // Displaying new lines
        Console.Write("Read month number and display number of days for that month:\n");  // Displaying the purpose of the program
        Console.Write("--------------------------------------------------------------");  // Displaying a separator
        Console.Write("\n\n");

        Console.Write("Input Month No : ");  // Prompting user to input a month number
        monno = Convert.ToInt32(Console.ReadLine());  // Reading the input and converting it to an integer

        switch(monno)  // Switch statement based on the entered month number
        {
            case 1:
            case 3:
            case 5:
            case 7:
            case 8:
            case 10:
            case 12:
                Console.Write("Month has 31 days. \n");  // Displaying that months 1, 3, 5, 7, 8, 10, and 12 have 31 days
                break;
            case 2:
                Console.Write("The 2nd month is February and has 28 days. \n");  // Displaying that February has 28 days
                Console.Write("In leap years, February has 29 days.\n");  // Mentioning that in leap years, February has 29 days
                break;
            case 4:
            case 6:
            case 9:
            case 11:
                Console.Write("Month has 30 days. \n");  // Displaying that months 4, 6, 9, and 11 have 30 days
                break;
            default:
                Console.Write("Invalid Month number.\nPlease try again ....\n");  // Handling invalid month numbers
                break;
        }
    }
}

Sample Output:

Read month number and display number of days for that month:
