How do you use a ‘for loop’ for accessing array elements in C#?

CsharpProgrammingServer Side Programming

The ‘for loop’ executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.

The following is our for loop.

Example

 Live Demo

using System;
namespace ArrayApplication {
   class MyArray {
      static void Main(string[] args) {
         int [] n = new int[10]; /* n is an array of 10 integers */
         int i,j;
         /* initialize elements of array n */
         for ( i = 0; i < 10; i++ ) {
            n[ i ] = i + 100;
         }
         /* output each array element's value */
         for (j = 0; j < 10; j++ ) {
            Console.WriteLine("Element[{0}] = {1}", j, n[j]);
         }
         int a = n[2];
         Console.WriteLine(a);
         Console.ReadKey();
      }
   }
}

Output

Element[0] = 100
Element[1] = 101
Element[2] = 102
Element[3] = 103
Element[4] = 104
Element[5] = 105
Element[6] = 106
Element[7] = 107
Element[8] = 108
Element[9] = 109
102

Now let’s say you need the third element. For that, use.

int a = n[1];

The above will give the third element i.e. 102.
