Jagged Arrays

Using Jagged Arrays, we can define any number of columns within a row of a two/multi-dimensional array.

Here is an example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing;
using System.Collections;


namespace ConsoleApplication6
{
    
    class Program
    {
        static void Main(string[] args)
        {
            int[][] jagged = new int[3][];

            jagged[0] = new int[2] { 10, 20 };
            jagged[1] = new int[6] { 30, 40, 50, 60, 70, 80 };
            jagged[2] = new int[3] { 90, 100, 110 };

            //Console.WriteLine(sizeof(int)*(2+6+3));

            for (int row = 0; row < jagged.Length; row++)
            {
              
              for(int col=0; col< jagged[row].Length; col++)
                {
                    Console.Write(jagged[row][col] + " ");
                }
                Console.WriteLine();
            }
        }
    }
}
