Accessing Array Elements

Accessing Array Elements

To access an element in an array, you specify its index, as shown in the following statements:

int[] num = new int[5] { 1, 2, 3, 4, 5 };
Console.WriteLine(num[0]); //---1---
Console.WriteLine(num[1]); //---2---
Console.WriteLine(num[2]); //---3--- 
Console.WriteLine(num[3]); //---4---
Console.WriteLine(num[4]); //---5--- 

The index of an array starts from 0 to n-1. For example, num has size of 5 so the index runs from 0 to 4.

You usually use a loop construct to run through the elements in an array. For example, you can use the for statement to iterate through the elements of an array:

for (int i = 0; i < num.Length; i++)
 Console.WriteLine(num[i]);

You can also use the foreach statement, which is a clean way to iterate through the elements of an array quickly:

foreach (int n in num)
 Console.WriteLine(n);
