C# Jagged array
A jagged array is an array of arrays.
A jagged array is a one-dimensional array.
You can declare one withintJagged array of valuesscores, as shown below:
int [][] scores;
to obtain the 2nd element of a (an array), then get the 3rd element from this integer array.
int[][] scores = new int[5][];
for (int i = 0; i < scores.Length; i++)
{
scores[i] = new int[4];
}
, that is, first evaluate a
int[][] scores = new int[2][]{new int[]{92,93,94},new int[]{85,66,87,88}};
Here, scores is an array composed of two integer arrays -- scores
Example
The following example demonstrates how to use a jagged array:
Example
using System;
namespace ArrayApplication
{
class MyArray
{
static void Main(string[] args)
{
/* A jagged array consisting of 5 integer arrays */
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 the value of each element in the array */
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();
}
}
}
namespace ArrayApplication
{
class MyArray
{
static void Main(string[] args)
{
/* A jagged array consisting of 5 integer arrays */
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 the value of each element in the array */
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();
}
}
}
When the above code is compiled and executed, it produces the following results:
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] = 8other extensions
