Static Arrays in C#

When we're dealing with large amounts of data, we want to make sure we can organize and manage it properly.

In C#, we use arrays to store several pieces of data in one place. The items in an array must be of the same data type.

A static array or fixed array is an array for which the size / length is determined when the array is created and/or allocated.

Creation:

We create a static array by using the keyword new, then writing the data type of the elements and the array's length inside []:

string[] arrayOfStrings = new string[3];

In this program we created an array named arrayOfStrings that consists of 3 string items.

These 3 items are null (no value given yet) initially.

Creation & Initialization:

There is a way to initialize an array at creation by using the = operator with an opening bracket, end it with a closing bracket, and put a comma between each entry, like this:

string[] arrayOfStrings = {"AlgoCademy", "coding", "static arrays"};

We created an array named arrayOfStrings which consists of 3 string items: "AlgoCademy", "coding" and "static arrays".
