Hi there,
Hello,
have a look at this example:
########################################################
#!/usr/local/bin/perl
use strict;
use warnings;
my $a_hash = { hund => "Dogge",
katze => "Perser",
obst => "Banane"
};
sub test($){
You really shouldn't use prototypes in perl:
http://groups.google.com/group/comp.lang.perl.modules/browse_frm/thread/4958701f6b5155a3/84484de5eb01085b
my $x = shift;
print $x->{katze}; # Is this the same
print $$x{"katze"}; # as this?
}
test($a_hash);
######################################################
Do the both "print" lines the same thing
or do they only result in the same thing?
They are both the same:
perldoc perlreftut
perldoc perlref
perldoc perllol
See also the section "CAVEAT ON PRECEDENCE" in:
perldoc perldsc
