jagged array

A jagged array is an array of arrays where the array elements are not necessarily of the same length. This differs from a rectangular array where the array elements must all be of the same length.

Here's a simple program which creates a two dimensional jagged array of integers and prints them to the console:

using System;

class Test

{

static void Main()

{

int[][] jagged = new int[2][];// jagged array has two elements

jagged[0] = new int[3]{1, 2, 3}; // first element as a length of 3

jagged[1] = new int[4]{1, 2, 3, 4}; // second element has a length of 4

foreach(int[] array in jagged)

{

foreach(int i in array) Console.Write("{0} ", i);

Console.WriteLine();

}

Console.ReadKey();

}

The output is:

1 2 3

1 2 3 4
