# C – Multi-Dimensional Array in C2 min read

## What is Multi-Dimensional Array in C?

In C programming, Multi-Dimensional Arrays refer to as array of arrays. This could be of 2D or 3D (two-dimensional or three-dimensional) Array. These arrays are stored in the form of a table (with rows and columns).

The general form of multi-dimensional array:

The data type must be a valid C data type, a unique name must be specified to each array and the size must be of an integer constant.

#### Initialization of multidimensional array.

We can initialize a Multi Dimensional Array (two-dimensional or three-dimensional) in the following ways in C.

1. Initialization of 2d Array

2. Initialization of 3d Array

#### Accessing Multi-Dimensional Array Elements in C

Accessing 2d Array:

An array can be accessed by using a specific index number. It can be achieved by placing the particular index number within the brackets [][]. Such as:

Accessing 3d Array:

Accessing 3-dimensional array is also as same as a two-dimensional array, the only difference is that in 3d array we have to specify 3 subscripts with a required index number.

## Example of two -dimensional Array in C:

Displaying the elements with index number from 2D Arrays.

Output: After executing the above code, the following result will be displayed.

## Example of three-dimensional Array in C:

Displaying the elements with index number from 3D Arrays.

Output: After executing the above code, the following result will be displayed.

As we saw the examples of 2D and 3D arrays, in a similar we can create any number dimension as required. However, the most used multidimensional array is a two-dimensional array.
