Bench test your PC!

Well, I was bored, so I made a C# app to calculate prime numbers.

.net 2.0 framework required.

Open it, enter:

1000000 (one million)

And wait for it to complete.

Then post the time it shows.

Tips: Close all background applications.

Note that it will get slower as the numbers get bigger.

And if it's taking up CPU, you should expect it!

Code:

using System;
using System.Diagnostics;


namespace StaticExtensionMethod
{


    class Test
    {

        static Stopwatch primes(int cap)
        {
            Stopwatch timer = new Stopwatch();
            timer.Start();
            for (int num = 2; num <= cap; num++)
            {


                int i;
                for (i = 2; i < num; i++)
                {
                    int n = num % i;
                    if (n == 0)
                    {
                        
                        break;
                    }
                }
                if (i == num)
                {
                    Console.WriteLine(num);
                }
            }
            timer.Stop();
            return timer;

        }





        public static void Main()
        {

            int cap = 0;
            int.TryParse(Console.ReadLine(), out cap);
            Console.WriteLine("End user input\r\n-------------\r\n\r\n");
            Stopwatch timeTaken = primes(cap);
            Console.WriteLine("{0}d, {1}h, {2}m, {3}s taken for {4} as cap", timeTaken.Elapsed.Days, timeTaken.Elapsed.Hours, timeTaken.Elapsed.Minutes, timeTaken.Elapsed.Seconds, cap);
            Console.ReadLine();
        }
    }
