An array is a fundamental data structure that is used to store a collection of elements of the same data type in a contiguous block of memory. Arrays are often used to represent collections of data such as lists, tables, matrices, or multidimensional structures. In this article, we will focus on the types of arrays based on their dimensions.<\/p>\n

Types Of Array<\/h2>\n

Arrays can be classified based on their dimensions, which refer to the number of indices required to access an element in the array. In this section, we will discuss two types of arrays: single-dimensional arrays and multi-dimensional arrays.<\/p>\n

Single Dimensional Array<\/h3>\n

A single-dimensional array is the simplest type of array that stores elements in a linear sequence. It is also known as a one-dimensional array<\/a>, and each element in the array can be accessed using a single index. The index ranges from 0 to the length of the array minus one.<\/p>\n

Syntax for Declaration of Single Dimensional Array<\/strong>
\nThe declaration syntax for the one-dimensional array is listed below.<\/p>\n

data_type array_name[array_size];\n\/\/Example\nint evenNumbers[5];<\/code><\/pre>\n
data_type :<\/strong> is a type of data for each block of an array.
\narray_name :<\/strong> is the array’s name, which we can use to refer to it.
\narray_size :<\/strong> is the number of memory array blocks will have.<\/p>\n
Initialization of Single Dimensional Array<\/strong>
\nA list of elements separated by commas and enclosed in curly brackets can be used to initialize an array.<\/p>\n
data_type array_name[array_size] = {element1, element2, element3, ......... , elementN};\n\/\/Example\nint evenNumbers[5] = {0, 2, 4, 6, 8};<\/code><\/pre>\n
Important Point:<\/strong> What happens if we supply less elements than the array can hold?<\/p>\n
In this case, the default value\u2014null for a string array, 0 for an integer array, etc.\u2014will be used to fill the remaining memory block. See the example in the section below for further details.<\/p>\n\t\t\t\t\t\t
