4. C# — Count Vowels in One Line

using System;

using System.Linq;

class Program
{
    static void Main()
    {
        string text = "Hello Florida";

        // Count vowels
        int vowelCount = text.Count(c => "aeiouAEIOU".Contains(c));

        Console.WriteLine($"Vowels: {vowelCount}");
    }
}

✅ Cool because:

  • Functional style.

  • Easy to adapt for consonants, digits, etc.

C# — Generate a Random String in One Line

  C# — Generate a Random String in One Line Most people use loops to build random strings, but here’s a fun way with LINQ : using System; using System.Linq; class Program {     static void Main()     {         // Generate a random 12-character string (letters + digits) in one line         string randomCode = new string(             Enumerable.Range(0, 12)                       .Select(_ => "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"[new Random().Next(36)])                       .ToArray()         );         Console.WriteLine($"Your unique code: {randomCode}");     } } ✅ What’s cool about it? Uses LINQ and Enumerable.Range instead of loops. Builds the string in a functional style . The source alphabet can be changed to includ...
