write c# program to read number of month from user, and prints the equavalent month name. solve it in 2 ways, first way using if else, second way using switch case

internal class Program
{
    private static void Main(string[] args)
    {
        //1st way: using if else:
        int monthnumber;
        Console.Write("enter month number (between 1 to 12): ");
        monthnumber = Convert.ToInt32(Console.ReadLine());
        if (monthnumber == 1)
            Console.WriteLine("JAN");
        else if (monthnumber == 2)
            Console.WriteLine("FEB");
        else if (monthnumber == 3)
            Console.WriteLine("MAR");
        else if (monthnumber == 4)
            Console.WriteLine("APRL");
        else if (monthnumber == 5)
            Console.WriteLine("MAY");
        else if (monthnumber == 6)
            Console.WriteLine("JUNE");
        else if (monthnumber == 7)
            Console.WriteLine("JULY");
        else if (monthnumber == 8)
            Console.WriteLine("AGUST");
        else if (monthnumber == 9)
            Console.WriteLine("SEP");
        else if (monthnumber == 10)
            Console.WriteLine("OCT");
        else if (monthnumber == 11)
            Console.WriteLine("NOV");
        else if (monthnumber == 12)
            Console.WriteLine("DECMP");
        else
            Console.WriteLine("invalid date");
    }
}

using switch statement:

internal class Program
{
    private static void Main(string[] args)
    {
        int monthnumber;
        Console.Write("enter month number (between 1 to 12): ");
        monthnumber = Convert.ToInt32(Console.ReadLine());
        switch (monthnumber)
        {
            case 1: 
                Console.WriteLine("JAN");
                break;
            case 2: 
                Console.WriteLine("FEB");
                break;
            case 3: 
                Console.WriteLine("MAR");
                break;
            case 4: 
                Console.WriteLine("APR");
                break;
            case 5:
                Console.WriteLine("MAY");
                break;
            case 6:
                Console.WriteLine("JUNE");
                break;
            case 7: 
                Console.WriteLine("JULY");
                break;
            case 8:
                Console.WriteLine("AGUST");
                break;
            case 9:
                Console.WriteLine("SEP");
                break;
            case 10:
                Console.WriteLine("OCT");
                break;
            case 11:
                Console.WriteLine("NOV");
                break;
            case 12:
                Console.WriteLine("DECM");
                break;
            default: 
                Console.WriteLine("invalid entry");
                break;
        }
    }
}
