دوستان این کد سی

        double[] n1 = new double[11000];

        double[] n2 = new double[11000];

        double[] y = new double[11000];

        long cun1 = 0;

        long cun2 = 0;

        long freq = 0;

        bool d;

        //[System.Security.SuppressUnmanagedCodeSecurity]

        [DllImport("kernel32")]

        private static extern bool QueryPerformanceFrequency(ref long  PerformanceFrequency);

        //[System.Security.SuppressUnmanagedCodeSecurity] // We won't use this maliciously

        [DllImport("kernel32")]

       



        private void button1_Click(object sender, EventArgs e)

        {

         



          d=  QueryPerformanceCounter(ref cun1);

            

            for (int m = 1; m < 100000; m++)

                for (int n = 0; n < 10000; n++)

                {

                    n1[n] = n;

                    n2[n] = n;

                    y[n] = n1[n] * n2[n];

                }

            QueryPerformanceCounter(ref cun2);

            QueryPerformanceFrequency(ref freq);

            label1.Text = ((float)(cun2 - cun1) / freq).ToString();



        }

اینم کد وی بی

Dim n1(11000), m1(11000), j(11000) As Double

    Dim c1, c2, frq As Double

    Dim n, m As Int32

    Declare Function QueryPerformanceCounter Lib "kernel32.dll" (ByRef x As Int64) As Byte

    Declare Function QueryPerformanceFrequency Lib "kernel32.dll" (ByRef x As Int64) As Byte

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click









        QueryPerformanceCounter(c1)

        For m = 1 To 100000

            For n = 0 To 10000



                n1(n) = n

                m1(n) = n

                j(n) = n1(n) * m1(n)

            Next

        Next







        QueryPerformanceCounter(c2)

        QueryPerformanceFrequency(frq)

        Label1.Text = (c2 - c1) / frq

    End Sub

فقط احتمال داره که تو نمونه ای که فایل اجراییش رو براتون گذاشته بودم تعدداد اجرای حلقه for با این یه کم متفاوت باشه

تاپیک این همه رفته جلو ولی هنوز کسی نگفته این دو تا کد معادل هم نیستن ؟

For m = 1 To 100000
For n = 0 To 10000



for (int m = 1; m < 100000; m++)
for (int n = 0; n < 10000; n++)

تعداد تکرار حلقه ها به طرز فجیعی با هم اختلاف دارن ! اگه سرعت ایندو برابر بود بیشتر جای تعجب داشت .
