✅ GetLength vs .Length

   static void Main(string[] args)
   {
       int[,,] ints = new int[,,] {

          { {1,2,3},
            {4,5,6},
            {7,8,9} },
          {
           {10,10,11},
           {11,12,13},
           {12,13,14}
           
           }

          
       };
       for (int i = 0; i < ints.GetLength(0); i++)
       {
           for (int j = 0; j < ints.GetLength(1); j++)
           {
               for(int k = 0; k < ints.GetLength(2); k++)
               {
                   Console.WriteLine(ints[i, j, k]);
               }
           }
       }
       Console.ReadLine();
   }

   static void Main(string[] args)
   {
       int[,,] ints = new int[,,] {

          { {1,2,3},
            {4,5,6},
            {7,8,9} },
          {
           {10,10,11},
           {11,12,13},
           {12,13,14}
           
           }

          
       };
       for (int i = 0; i < ints.GetLength(0); i++)
       {
           for (int j = 0; j < ints.GetLength(1); j++)
           {
               for(int k = 0; k < ints.GetLength(2); k++)
               {
                   Console.WriteLine(ints[i, j, k]);
               }
           }
       }
       Console.ReadLine();
   }

the thing is .GetLength(0) doesn't need a -1 in the end while in .Length we do it like .Length-1

question about strings & stringbuilder!

this is the code

namespace Palindrome_Finder
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Welcome to Our Palindrome Finder");
            Console.WriteLine("Enter a Word or a Sentence to find if it's a Palindrome");
            string UserInput = Console.ReadLine();
            string processedInput=cleaner(UserInput);
            Console.WriteLine($"Reversed Input: {processedInput}");
            Console.ReadLine();

        }
        static string cleaner(string input)
        {
            string cleanedInput = input;
            Console.WriteLine($" Original Input:{cleanedInput}");
            foreach (char c in cleanedInput)
            {
               
                if(char.IsLetterOrDigit(c))
                {
                   cleanedInput.Append(c);
                }
               
            }
            string reversedInput = new string(cleanedInput.Reverse().ToArray());
            return reversedInput;

        }

    }
}

namespace Palindrome_Finder
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Welcome to Our Palindrome Finder");
            Console.WriteLine("Enter a Word or a Sentence to find if it's a Palindrome");
            string UserInput = Console.ReadLine();
            string processedInput=cleaner(UserInput);
            Console.WriteLine($"Reversed Input: {processedInput}");
            Console.ReadLine();

        }
        static string cleaner(string input)
        {
            string cleanedInput = input;
            Console.WriteLine($" Original Input:{cleanedInput}");
            foreach (char c in cleanedInput)
            {
               
                if(char.IsLetterOrDigit(c))
                {
                   cleanedInput.Append(c);
                }
               
            }
            string reversedInput = new string(cleanedInput.Reverse().ToArray());
            return reversedInput;

        }

    }
}

people say me use stringbuilder instead of appending to a string they say the way I did can be slower and resource consuming he don't reply further thought he is busy man can any gentleman teach me why is it he just said strings are immutable which is also what I don't think cuz I can add new value to strings I can assign new value to strings why they say they are immutable! help me this is confusing for me!

seems like this doesn't work as intended!

        static void Main(string[] args)
        {
            Console.WriteLine("Welcome to our Words Counter");
            Console.Write("Put your paragraphs here to get words number's count: ");
            string userInput = Console.ReadLine();

            List<string> words = new List<string>();
            string word = "";

            for(int i=0; i<=userInput.Length-1;i++)
            {
                if (userInput[i]==' ')
                {
                   if(!string.IsNullOrWhiteSpace(word))
                    {
                        words.Add(word);
                        word = "";
                    }
                }
                else
                {
                    word += userInput[i];
                }

                //Adds the last word if the input doesn't end with a space 
                if (!string.IsNullOrWhiteSpace(word))
                {
                    words.Add(word);

                }
            }
            Console.WriteLine($"The ammount of words in your input are: {words.Count}");
            Console.ReadLine();
        }
    }

It just counts character while I made it to count words! unable to spot the issue haven't spent more than 3 minutes to spot but thought of sharing it over here! I am sorry for that
