How do you declare jagged arrays in C#
A Jagged array is an array of arrays. You can declare a jagged array named scores of type int as.
int [][] scores;
Let us now see an example to learn how to declare and work with jagged arrays in C#.
Example
using System;
namespace ArrayApplication {
class MyArray {
static void Main(string[] args) {
/* a jagged array of 5 array of integers*/
int[][] a = new int[][]{new int[]{0,0},new int[]{1,2}, new int[]{2,4},new int[]{ 3, 6 }, new int[]{ 4, 8 } };
int i, j;
/* output each array element's value */
for (i = 0; i < 5; i++) {
for (j = 0; j < 2; j++) {
Console.WriteLine("a[{0}][{1}] = {2}", i, j, a[i][j]);
}
}
Console.ReadKey();
}
}
}Output
a[0][0] = 0 a[0][1] = 0 a[1][0] = 1 a[1][1] = 2 a[2][0] = 2 a[2][1] = 4 a[3][0] = 3 a[3][1] = 6 a[4][0] = 4 a[4][1] = 8
