Two-dimensional arrays, three-dimensional arrays, four-dimensional arrays, and more are all examples of multi-dimensional arrays... The two-dimensional array is the most popular and widely used multi-dimensional array. Data is stored in the form of a table using 2-D arrays.
Arrays can be classified into three types: indexed arrays, multidimensional arrays, and associative arrays.
An array of arrays can be defined as a two-dimensional array. The matrices that make up the 2D array are represented as a collection of rows and columns. 2D arrays, on the other hand, are used to build a data structure that resembles that of a relational database.
A one-dimensional array is a structured collection of components (commonly referred to as array elements) that may be accessed separately by specifying a single index value for each component's position.
Arrays are a form of data structure that can hold a fixed-size collection of elements of the same type in a sequential order. Although an array is used to hold data, it is often more beneficial to conceive of it as a collection of variables of the same type. All arrays are made up of memory regions that are connected in some way.
