Arrays that contain only one subscript are called one-dimensional arrays. It is used to store data in linear form.

2:- two dimensional(2-D) arrays:-

The arrays in which there are two subscripts are called two dimensional arrays. Two dimensional arrays are also called matrix and table.

3:- Multi dimensional(M-D) arrays:–

The arrays which contain more than two subscripts are called Muti-dimensional arrays.

Applications of Array

• They are used to implement mathematical vectors and matrices.
• They are used to implement rectangular tables.
• Arrays are used to implement Heaps, Hash, Tables, Deques, Queues, Stacks and Strings.
• They are used as a compact alternative to multiple statements to determine the complete or partial control flow of a program.

Types of Indexing in array

• 0 (Zero Based Indexing)
• 1 (One Based Indexing)
• n (n–Based Indexing)

Advantages of Array

• It stores the same type of data.
• We only have to remember the first index of the array.
• It is also used to implement elements like Stack, Graph, Queue.
• Multiple values can be easily stored in this.

Disadvantages of Array

• The time complexity increases in inserting and deleting any operation.
• It is fixed in size, due to which the problem of memory wastage also arises.
• If you have enough space in your memory but it is not in contiguous form then you cannot initialize the array.
• In this, once you choose the size of the array, then you cannot edit it later.
