How to Declare an Integer Array in Perl - Step by Step Examples

How to Declare an Integer Array in Perl ?

Answer

To declare an integer array in Perl, you can use array literal notation or the qw() operator.


✐ Examples

1 Declare and Initialize an Integer Array

In this example,

  1. We declare an integer array named @numbers with predefined values using array literal notation.
  2. We print the array to demonstrate the initialization.

Perl Program

@numbers = (1, 2, 3, 4, 5);
print "Integer Array: [@numbers]\n";

Output

Integer Array: [1 2 3 4 5]

2 Declare an Empty Integer Array

In this example,

  1. We declare an empty integer array named @empty_array using the qw() operator.
  2. We print the array to demonstrate the declaration.

Perl Program

@empty_array = qw();
print "Empty Integer Array: [@empty_array]\n";

Output

Empty Integer Array: []
