Hi
I am a newbie to Perl , I was reading through one of the beginner level
books on perl. I did not understand the concept of "Callbacks" and i
have the following questions on it:
1. What are they ?
2. Why do we need them ?
3. What useful purpose do they achieve ?
I was reading the following code to understand it but could not comprehend.
*Code:*
#!/usr/bin/perl
use warnings;
use strict;
use File::Find;
find ( \&callback, "/");
sub callback {
print $File::Find::name, "\n";
}
*End Of Code:*
Thanks
