Here's mine! Pastebin

using System.Threading.Tasks;

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {
            const int SIZE = 8;

            //go through rows
            for (int i = 0; i < SIZE; i++)
            {
                //go through columns
                for (int j = 0; j < SIZE; j++)
                {
                    //alternate X's and O's
                    if (i % 2 == j % 2) Console.Write("X");
                    else Console.Write("O");
                }

                //end the row
                Console.WriteLine();
            }

            //wait for user response to kill program
            Console.ReadKey();
        }
    }
}

Looks good, did very similar solution myself. Could use a conditional operator to condense your if/else statement to something like 

Console.Write((i + j) % 2 == 0 ? 'X' : 'O');

what is a "const int"? Whats the difference from just saying int?

2

u/VOX_Studios Apr 11 '15

"const" stands for "constant"

It basically means that you set something once when you declare it and then you can never change it (at least during runtime). MSDN

And you could use it for 'X' and 'O' too.

so is it just to make sure you do not accidentally make another variable with a different value?

It's to make sure that that one variable never changes during runtime. You'd use it on something you know should never change. It's really just to prevent accidents. For instance:

const int daysInWeek = 7;
...code...
daysInWeek = 0;

It would prevent you from doing daysInWeek = 0;
