Jagged Array Example

Jagged Array is arrays of array in .NET Framework. Below is the example to create Jagged Array in C#.

int [][] jaggedArray = new int [5][];
jaggedArray[0] = new int [5];
jaggedArray[1] = new int [6];
jaggedArray[2] = new int [7];
jaggedArray[3] = new int [8];
jaggedArray[4] = new int [9];

Above declaration creates 2 Dimensional array with different lengths for each row. These index shows the size arrays are and referenced as Jagged Arrays.

The below code shows example of Jagged array in C#.

using System;public class JaggedArrayExample
{ 
public static void Main() 
{ 
// Declaration of Jagged Array
int [][] jaggedArray = new int [5][]; 
jaggedArray[0] = new int [5]; 
jaggedArray[1] = new int [6]; 
jaggedArray[2] = new int [7]; 
jaggedArray[3] = new int [8];
jaggedArray[4] = new int [9]; 
Console.WriteLine("Enter numbers for Jagged Array to display"); 
for(int i=0 ; i < jaggedArray.Length ; i++) 
{ 
for(int j=0 ; j < jaggedArray[i].Length ; j++) 
{ 
String arrStr= Console.ReadLine(); 
int n=Int32.Parse(arrStr); 
jaggedArray[i][j]= n; 
} 
} 
Console.WriteLine("Result of Jagged Array Elemnts are like below for the entered number"); 
for(int i=0 ; i < jaggedArray.Length ; i++) 
{ 
for(int j=0 ; j < jaggedArray[i].Length ; j++) 
{ 
Console.Write(jaggedArray[i][j]+" "); 
} 
Console.WriteLine("\t"); 
} 
}
} 

Hope this help to beginner to understand Jagged Array concept in C#.
