Question

I have an array where the index starts at 0. I am attempting to determine how I find specific items in array.

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

I only want 2,6,10,14. If it wasn’t a 0-index array I could do a modulus%3 on the index and get what I want but I cannot figure out how to do it.

    string[] arr = new string[16];
    arr[0] = "data";
    arr[1] = "data";
    arr[2] = "data";
    arr[3] = "data";
    arr[4] = "data";
    arr[5] = "data";
    arr[6] = "data";
    arr[7] = "data";
    arr[8] = "data";
    arr[9] = "data";
    arr[10] = "data";
    arr[11] = "data";
    arr[12] = "data";
    arr[13] = "data";
    arr[14] = "data";
    arr[15] = "data";
    for (int i = 0; i < arr.Length; ++i)
    {
        if (i % 3 == 0)
        {
            Console.WriteLine(arr[i]);
            Console.ReadLine();
        }
    }
    Console.ReadLine();

This of course doesn’t work for me and I’ve tried manipulating ‘i’ but I just haven’t had enough coffee yet today to get it to work.

Answer 1

It looks like you want

if(i % 4 == 2)
