How to create, initialize and print 2D array of ints in C#

Answer 1

using System;

namespace ConsoleApplication_C_Sharp
{
    class Program
    {
        static void Main(string[] args)
        {
            int[,] arr2d = new int[,]
            {
                {123, 87},
                {55, 13},
                {3, 98873},
            };

            Console.WriteLine(arr2d[0, 0]);
            Console.WriteLine(arr2d[0, 1]);

            Console.WriteLine(arr2d[1, 0]);
            Console.WriteLine(arr2d[1, 1]);

            Console.WriteLine(arr2d[2, 0]);
            Console.WriteLine(arr2d[2, 1]);
        }
    }
}
