What is an Array & Types of Arrays

What is an Array?

An array is a non-primitive and linear data structure that is a collection of similar data items. This means it will only store data of the same type, such as all integer data or all floating-point data. The array data structure is used to store a group of data objects.

"Arrays are static data structures, meaning we can only allocate memory at compile time and cannot change it at run-time."

Types of Arrays

Arrays are of the following three types:

1. One-Dimensional (1-D) Arrays:
An array with only one subscript is called a one-dimensional array. It is used to store data in a linear fashion.

2. Two-Dimensional (2-D) Arrays:
An array with two subscripts is called a two-dimensional array. Two-dimensional arrays are also called matrices and tables.

3. Multi-Dimensional (M-D) Arrays:
Arrays with more than two subscripts are called multi-dimensional arrays. They are useful for storing more complex data structures.

Benefits of Array Data Structure

The array data structure offers several benefits, such as:

  • Storing data in an organized manner.
  • Efficiently accessing and manipulating data.
  • Making it easy to work with data of the same type.

Where are Arrays Used?
Arrays are used in many types of applications, such as:

  • Database systems
  • Image processing
  • Scientific computing
  • Game development

This information provides a comprehensive understanding of the array data structure and how it can be used in various scenarios.
