Hi, When I learning to print array variables, I found the white space inserted when double quoter used. Snippet code as below. Could you please tell me why?
#!/usr/bin/perl -w
use strict;
use warnings;
my @str_array = ("Perl","array","tutorial");
my @int_array = (5,7,9,10);
print @str_array;
print "\n";
# added the double quotes
print "@str_array";
print "\n";
print @int_array;
print "\n";
# added the double quotes
print "@int_array";
Output:
Perlarraytutorial
