when i axsess a value from an hash it dose nothing

[atbusbook]

%foo = {i=>1,b=>2};
print $foo{i};

its output == ""

 

[David Squire]

%foo = {i=>1,b=>2};
print $foo{i};

its output == ""

You've used the wrong sort of brackets:

perl -e '%foo = (i => 1,b => 2); print $foo{i}'

Further clarification: {} returns a reference to a hash, so this works:

perl -e '$foo = {i => 1,b => 2}; print $$foo{i}'

%foo = {i=>1,b=>2};

That's not how you declare a hash. Please ask perl to help you before you
ask others to do so:

use strict;
use warnings;
my %foo = {i=>1,b=>2};
my %bar = (i=>1,b=>2);
