Perl Array - Create empty size array, assign zero or space with code examples

This tutorial explains multiple ways

create an empty-sized array with a length of zero
create and initialize an array with elements containing zero
create and initialize an array with elements containing space

How to create an empty array with zero elements in Perl

The empty array can be created in two ways

Declare an Array variable the variable is declared using the my keyword, followed by a variable prefixed with @.

my @numbers;

It creates a new array with an empty(zero sizes)

Assign with empty size

Another way to create an empty array is by assigning ()

In both cases above, It creates an empty list with a new array reference.

Here is an example

#Declare array variable
my @numbers;
print @numbers;

## Declare and assign an empty list
my @numbers1=();
print @numbers1;

Output empty array

how to create an array with initialized with zero values

the array can be assigned with elements containing zero using multiplier syntax.

syntax

(element) x n

element is an element that is populated into an array. to create an array with elements zero, use (0). x is a multiplier operator n tells the number of elements to populate

my @numbers1 = (0) x 4;
print @numbers1;

How to create an array assigned with empty spaces

the array can be assigned with empty spaces using multiplier syntax.

syntax

(element) x n

element is an element that is populated into an array. to create an array with empty spaces, use ("") n tells the number of elements to populate x is a multiplier in perl

Here is an example

my @numbers1 = (" ") x 5;
print @numbers1;

How do I initialize an array in Perl?

To initialize an array, Please follow the below steps.

Declare an array variable using the @ prefix
Arrays contain any scalar values such as string, numbers, floating numbers
Assign an array using a list of values enclosed in ()

for example, a list of numbers is initialized in an array as given below

my @numbers=(1,2,3,4,5,6,7,8,9,10)
