FreeKB - Perl Count values in an array
Perl - Count values in an array

Let's say you have an array that contains 4 values.

my @array = qw(value1 value2 value3 value4);

 

In this example, the $count variable will contain the number of elements in @array.

my $count = @array;

 

You can print the $count variable;

print $count;

 

Which will return 4, meaning there are 4 values in @array.

4

 

Additionsubtraction, division, and multiplication can be used to adjust the count, like this.

my $count = @array + 1;

 

Or like this.

my $count = @array;
$count = $count + 1;
