How to check if an Array is Not Empty in Perl

How to check if an Array is Not Empty in Perl ?

In Perl, you can use the scalar function to check if an array is not empty.

In this example,

We create an array named @numbers with some elements.
We check if the array is not empty by using the scalar function on the array, and store the result in the variable $notEmpty.
Finally, we print whether the array is not empty or not.

@numbers = (1, 2, 3);
$notEmpty = scalar(@numbers);
print "Array is not empty: ", $notEmpty ? 'true' : 'false', "\n";

Array is not empty: true

In this example,

We create an empty array named @emptyArray.
We check if the array is not empty by using the scalar function on the array, and store the result in the variable $notEmpty.
Finally, we print whether the array is not empty or not.

@emptyArray = ();
$notEmpty = scalar(@emptyArray);
print "Array is not empty: ", $notEmpty ? 'true' : 'false', "\n";

Array is not empty: false
