Average challenge

Hi,

I finished the Averager challenge, it works but I wonder if the code I've written is a good practice or bad practice, please let me know.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Averager_v2
{
    class Program
    {
        static void Main()
        {
            var sumOfEntries = 0.0;
            var sumLenght = 0.0;

            while (true)
            {

                Console.WriteLine("Enter a number or type \"done\" to see the average:");
                var userEntry = Console.ReadLine();

                if (userEntry.ToLower() == "done")
                {
                    break;
                }

                try
                {
                    var userNumbers = double.Parse(userEntry);

                    sumOfEntries += userNumbers;
                    sumLenght += +1.0; // adds the numbers of entries 

                }

                catch(FormatException)
                {
                    Console.WriteLine("Please imput numbers");
                    continue;
                }

            }

            var avrageOfEntry = sumOfEntries / sumLenght;
            Console.WriteLine(avrageOfEntry);

            Console.WriteLine("Goodbye");

            System.Threading.Thread.Sleep(5000);//make the console wait before exiting

        }
    }
}

I'm not sure what course this was for, or what instructions and initial code you were given. But the few areas for possible improvement I see are:

  • a "continue" is not needed if it's the last instruction in a loop
  • "sumLenght" might have been spelled "sumLength" (it works as-is because it is used consistently)
  • asking for and waiting on a keystroke to dismiss a window might be preferable to a fixed delay

These are all minor points, good job overall. :+1:
