How to store value in array
An array is a group of similar type of elements which has contiguous memory location. An array is a collection of like-typed variables that are stated to by a common name.
This tutorial will briefly discover how to store value in an array in the commonly used languages.
1. C Language
All arrays are the contiguous block of memory locations. By default, the lowest position of the array stores the first element, and the highest position stored the last data. In C, the array is declared by specifying the element's type and the total length of array required to store the data.
Syntax for declaring array
Syntax for initializing for storing array values
Element stored at position  = 10 Element stored at position  = 11 Element stored at position  = 12 Element stored at position  = 13 Element stored at position  = 14 Element stored at position  = 15 Element stored at position  = 16 Element stored at position  = 17 Element stored at position  = 18 Element stored at position  = 19 Element stored at position  = 20
Multidimensional Array in C
In C language, the elements of a 2 D (two-dimensional) array are accessed with the help of subscripts, i.e., the row index number and the column index number of the array.

Syntax for Initializing Two-Dimensional Arrays
Data stored in 2D array = 1 Data stored in 2D array = 0 Data stored in 2D array = 1 Data stored in 2D array = 2 Data stored in 2D array = 2 Data stored in 2D array = 4 Data stored in 2D array = 3 Data stored in 2D array = 6
2. C++ Language
In C++ language the user needs to specify the element type and total length of array.
Syntax to Declare Array
Syntax to initialize array
array at position: 1 array at position: 7 array at position: 50 array at position: 6
C++ language also enables the Multidimensional arrays.
Syntax for initializing 2D array
array at position: 1 array at position: 0 array at position: 0 array at position: 2 array at position: 2 array at position: 3 array at position: 5 array at position: 6
In Java language, Arrays work differently than what they used to do in C or C++ language.
To declare an array, the user needs to have two primary components: the type and the array's name.
The 'Type' refers to the elementary type of a specific array. It determines the data type of all elements that are included in the array. It comprises the array of primitive data types, unlike integers, char, float, double, etc., or it could include the user-defined data types (objects of a class) as well. Therefore, the element type for the array concludes what kind of data the array will contain.
Store values in one-dimensional array
Assigning values to an element in an array is similar to assigning values to scalar variables.
NOTE: It the array element is not assigned any value, by default it has a Null (empty) value.

Arrays of Objects
An array of objects is constructed in the same way as an array of primitive type data elements.
Element at 0 : 111 Varun Element at 1 : 121 Sukla Element at 2 : 131 Virat Element at 3 : 141 Anuskha Element at 4 : 151 Mohit
Multidimensional arrays are termed 'arrays of arrays' as they can hold each element of an array with the reference of another array. These are also known as Jagged Arrays. A multidimensional array is constructed by adding a set of square brackets () per dimension.

PHP array is an ordered map (holds elements on the base of the key-value). It is utilized to hold multiple values of a similar data type in a single variable.
PHP contains 3 kinds of array that are as follows:
1. Indexed Array
PHP index is described by an integer number that begins with 0 (default value). The PHP array can store any data type, such as numbers, characters, strings, and objects. All PHP array data are allocated an index number by default.

Colours are: Red, White, Black, Yellow
2. Associative Array
In PHP, the user can associate any specific name with each array elements using the '=>' symbol.

3. Multidimensional Array
Multidimensional arrays in PHP are also termed as "array of arrays". It enabled the user to store array data in a tabular format. PHP multidimensional array can be expressed in the form of a matrix which is denoted by row * column.

Python uses a module named 'Array' to handle all the functions of Arrays in Python. It is helpful when the user wants to manipulate only particular data values. Given below are the keywords that are important to learn the concept of an array in Python:
First array value: 20 Second array value: 40 Second last array value: 80
