Hi,

I have this code:

C#

private void btn_Click(object sender, EventArgs e)
{
    byte[] data = File.ReadAllBytes("a.txt");

    int[] totals = new int[256];

    foreach (byte in data)
    {
        ++totals[b];
    }
}

The output is this: http://i45.tinypic.com/2nquqhi.png[^]

But how can i show the frequency(occurrence) of each character in a.txt also?
and store it in: long[] freqar=new long[256];

Solution 1

No! Do this:

C#

foreach(byte value in data)
    ++totals[value];

Can you see you bug now? Now you have occurrences. Hope you can continue and calculate frequency by yourself.
