Answer 1

using System;

namespace ConsoleApplication_C_Sharp
{
    class Program
    {
        static void Main(string[] args)
        {
            string[, ] arr2d = new string[, ]
            {
                {"c#", "java"},
                {"c", "c++"},

            };

            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]);
