**What Is Array and Types of Array in Data Structure?**

An array is a data structure that stores a fixed-size sequence of elements of the same type. It is a fundamental concept in computer programming and is widely used to organize data efficiently. In this article, we will explore what arrays are and the different types of arrays in data structures.

## Understanding Arrays

An array is a collection of elements, where each element can be accessed using an index. The index represents the position of an element within the array. Arrays provide a convenient way to store and access multiple values using a single variable.

**Example:**

int[] numbers = {1, 2, 3, 4, 5};

In the above example, we have created an integer array named “numbers” with five elements. The elements are initialized with the values 1, 2, 3, 4, and 5. The index starts from 0, so numbers[0] represents the first element (1).

## Types of Arrays

There are several types of arrays based on their dimensions and functionality:

### 1. One-Dimensional Array

- A one-dimensional array is the simplest form of an array that stores elements in a linear sequence.
__Example:__

int[] marks = {90, 85, 95, 80};

In the above example, “marks” is a one-dimensional integer array that stores four marks.
The elements can be accessed using their respective indices: marks[0], marks[1], marks[2], marks[3].
### 2. Two-Dimensional Array

- A two-dimensional array is a collection of elements organized in rows and columns.
__Example:__

int[][] matrix = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

In the above example, “matrix” is a two-dimensional integer array with three rows and three columns.
The elements can be accessed using their row and column indices: matrix[0][0], matrix[0][1], matrix[1][2], etc.
### 3. Multidimensional Array

- A multidimensional array is an array with more than two dimensions.
__Example:__

int[][][] cube = {{{1, 2}, {3, 4}}, {{5, 6}, {7, 8}}};

In the above example, “cube” is a three-dimensional integer array with two layers, each containing two rows and two columns.
The elements can be accessed using their respective indices: cube[0][0][0], cube[1][1][1], etc.
Arrays play a crucial role in data structure because they provide efficient storage and retrieval of data. Understanding the different types of arrays allows you to choose the appropriate data structure based on your specific requirements.

In conclusion, an array is a fundamental concept in programming that allows us to store multiple values under one variable. We explored one-dimensional arrays, two-dimensional arrays, and multidimensional arrays in this article. By understanding these types of arrays in data structures, you can design efficient algorithms and solve complex problems effectively.

What Is Array in Data Structure? An array is a fundamental data structure in computer programming. It is a collection of elements of the same type that are stored in a contiguous block of memory.

In data structure, an array is a collection of elements of the same type that are stored in contiguous memory locations. It is one of the most commonly used data structures in programming and provides efficient ways to store and access multiple values. Definition of Array
An array can be defined as a fixed-size container that can hold a specific number of elements.

Array in Data and File Structure
An array is a fundamental concept in computer science and data structures. It is a linear data structure that stores a collection of elements of the same type. Each element in the array is assigned a unique index, which allows for efficient access to individual elements based on their position within the array.

What Is Array in Data Structure Example? In computer science, an array is a data structure that stores a fixed-size sequential collection of elements of the same type. Each element in an array is identified by its index, which is a non-negative integer value.
