Why is there no C# example?

I'm disappointed that there is no C# code here!!!

Hi there! I feel like that's a typo. I feel like the section marked as "C" should have been marked as "C#" given that it uses classes/objects found in the C# language. ANSI C is not object-oriented.

Hope this helps! :sparkles:

Whoops! It was marked C# but turns out its stripped out of the resulting Markdown. Who knew!

Here is a link to a simple linear search in C#. All the logic is written in the main function (which is not advisable), but one can see what is going easier. Raw code below. 

using System;


// Source: https://www.c-sharpcorner.com/blogs/linear-search-in-console-application1

namespace LinearSearch
{
    class Program
    {
        static void Main()
        {
            var numberArray = new int[100];
            Console.WriteLine("Enter the number of elements");

            string userInputElements = Console.ReadLine();
            int usersNumbers = Int32.Parse(userInputElements);

            Console.WriteLine("---------------------------");

            Console.WriteLine("\n Enter the array elements. Press enter/return after each number \n");

            for (int i = 0; i < usersNumbers; i++)
            {
                string usersInputNumbers = Console.ReadLine();
                numberArray[i] = Int32.Parse(usersInputNumbers);

            }

            Console.WriteLine("---------------------------");

            Console.WriteLine("Enter the Search element\n");

            string usersSearchElement = Console.ReadLine();
            int usersSearchNumber = Int32.Parse(usersSearchElement);

            for (int i = 0; i < usersNumbers; i++)
            {
                if (numberArray[i] == usersSearchNumber)
                {
                    Console.WriteLine("---------------------------");
                    Console.WriteLine("Search successful!");
                    Console.WriteLine("Element {0} found at location {1}\n", usersSearchNumber, i + 1);

                    Console.ReadLine();
                }
            }

            Console.WriteLine("Entered element not found.  Search unsuccesful.");
            Console.ReadLine();
