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.
