Declaration of Array
Arrays can be declared in various ways in different languages. For better illustration, below are some language-specific array declarations:
// This array will store integer type element
int arr[5];
// This array will store char type element
char arr[10];
// This array will store float type element
float arr[20];
// This array will store integer type element
int arr[5];
// This array will store char type element
char arr[10];
// This array will store float type element
float arr[20];
// This array will store integer type element
int arr[];
// This array will store char type element
char arr[];
// This array will store float type element
float arr[];
import array
# This array will store integer type element
arr = array.array('i')
# This array will store char type element
arr = array.array('b')
# This array will store float type element
arr = array.array('f')
// This array will store integer type element
int[] arr;
// This array will store char type element
char[] arr2;
// This array will store float type element
float[] arr3;
// JS code
let arr=[]
