So what's a good, simple algorithm to create a loop in C# where every time a certain value appears in an array it adds 1 to a counter in another array?

For example I have this:

```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication22
{
    class Program
    {
        const int SIZE = 12;

        static void Main(string[] args)
        {
            int[] numbers = new int[SIZE] {5, 5, 5, 7, 7, 7, 9, 7, 9, 9, 9, 1};
           string[] letters = new string[SIZE] { "m", "m", "s", "m", "s", "s", "s", "m", "s", "s", "s", "s" };
            int[] values = new int[SIZE] {15, 22, 67, 45, 12, 21, 24, 51, 90, 60, 50, 44};
            string[] status = new string[SIZE] { "f", "m", "f", "a", "m", "f", "f", "f", "m", "f", "m", "f" };

            int[] Count = new int[4];
            int x = 0;
            int i = 0;

            for (i = 0; i < SIZE - 1; i++)
            {
                if (numbers[i] > 0 && numbers[i] < SIZE)
                {
                    x = Count[i];
                    Count[x]++;
                }
            }

            for (i = 0; i < 4; i++)
            {
                Console.WriteLine("{0}", Count[4]);
            }
        }
    }
}

```

I am only counting the number of times 4 numbers appear in the numbers array. Someone suggested I use the method in the first loop but it doesn't seem to be working and creates an error that the index is out of bounds in the array. I want to display the number of times each of those numbers(5, 7,9 and 1) appear in 4 rows.

EDIT: Without using LINQ or any other fancy thing like Dictionary or whatever.
