How to initialize jagged arrays in C#?
Jagged array is an array of arrays. You can declare a jagged array named marks of type int as −
int [][] marks;
Initialize the jagged array as −
int[][] marks = new int[2][]{new int[]{92,93,94},new int[]{85,66,87,88}};The marks is an array of two array of integers.
- marks[0] is an array of 3 integers
- marks[1] is an array of 4 integers.
The following is an example displaying how to use jagged arrays and create an array of three arrays of integers.
Example
using System;
namespace Demo {
class Program {
static void Main(string[] args) {
/* a jagged array of 3 array of integers*/
int[][] a = new int[][]{new int[]{0,0},new int[]{1,2},new int[]{2,4} };
int i, j;
/* output each array element's value */
for (i = 0; i < 3; 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
