Single Dimensional Arrays in C#

C# Arrays

Like other programming languages, array in C# is a group of similar types of elements that have contiguous memory location. In C#, array is an object of base type System.Array. In C#, array index starts from 0. We can store only fixed set of elements in C# array.

C# Array Types

There are 3 types of arrays in C# programming:

1. Single Dimensional Array
2. Multidimensional Array
3. Jagged Array

In this tutorial we will learn more about Single Dimensional or 1D Arrays.

C# Single Dimensional Array

To create single dimensional array, you need to use square brackets [] after the type.

int[] arr = new int[5]; //creating array of size 5

You cannot place square brackets after the identifier.

NOTE:

• Array indices always start from 0. That is, the first element of an array is at index 0.
• If the size of an array is n, then the last element of the array will be at index n-1.

We can access the element of an array using the index number. Here is the syntax for accessing elements of an array,

// access array elements
array[index]

Similarly, we can print the contents of the any i^th cell with the following code:

System.Console.Write(array[i]);

Similarly, we can get the size of any array using the following code:

arrayName.Length

Task:

Take N integers as an input and store them in an array and then print the array in reverse format.
