C# Exercise: 60 Vowel - switch

using System;  // Import the System namespace to use basic classes like Console

class Program  // Define the main class of the program
{
    static void Main()  // The entry point of the program
    {
        // Ask the user to enter a symbol
        Console.Write("Enter a symbol: ");  // Display prompt for symbol input
        char symbol = Console.ReadKey().KeyChar;  // Read a single character input from the user

        // Move to the next line after the symbol input
        Console.WriteLine();

        // Use switch to determine if the symbol is a vowel, digit, or other symbol
        switch (symbol)
        {
            case 'a':  // If the symbol is 'a'
            case 'e':  // If the symbol is 'e'
            case 'i':  // If the symbol is 'i'
            case 'o':  // If the symbol is 'o'
            case 'u':  // If the symbol is 'u'
                Console.WriteLine("It is a vowel.");  // Display message for vowel
                break;

            // Check if the symbol is a digit
            case '0':
            case '1':
            case '2':

                break;

            // If the symbol is neither a vowel nor a digit
            default:
