Question

my test.pl script as below.

#!C:\Perl\bin\perl.exe
use strict;
use warnings;


sub printargs
{
    print "@_\n";
}

&printargs("hello", "world"); # Example prints "hello world"

If I replaced printargs("hello", "world"); with print($a, $b);.

How to pass ‘hello’ ,’world’ to $a , $b when I run perl test.pl hello world at command line, Thanks.

Answer 1

$ARGV[0] contains the first argument, $ARGV[1] contains the second argument, etc.

$#ARGV is the subscript of the last element of the @ARGV array, so the number of arguments on the command line is $#ARGV + 1.
