Random Letters - 2 Approaches

//Approach 1

using System;

namespace RandomLetters
{
    class Program
    {
        static void Main(string[] args)
        {
            Random random = new Random();

            for (int i = 0; i <10; i++)
            {
                int randomLetter = random.Next(65, 91);
                Console.WriteLine((char)randomLetter);
            }

            Console.ReadLine();
        }
    }
}


//Approach 2

using System;

namespace RandomLetters
{
    class Program
    {
        static void Main(string[] args)
        {
            Random random = new Random();

            // create a new array called alphabet, and assign it the value of the string alphabet.ToCharArray
            char[] alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray();

            for(int i = 0; i < 10; i ++)
            {
                int randomLetter = random.Next(0, alphabet.Length);
                Console.WriteLine(alphabet[randomLetter]);
            }

            Console.ReadLine();
        }
    }
}
