Jagged Arrays In C#

A jagged array is an array whose elements are arrays. The elements of a jagged array can be of different dimensions and sizes. A jagged array is sometimes called an "array of arrays." The following examples show how to declare, initialize, and access jagged arrays.

// Single-dimensional array
int[] numbers = new int[5];

// Multidimensional array
string[,] names = new string[5,4];

// Array-of-arrays (jagged array)
int[][] jaggedArray = new int[3][];

jaggedArray[0] = new int[5];
jaggedArray[1] = new int[4];
jaggedArray[2] = new int[2];
