[Ilugc] [TIP] perl tutorial XI (perl references)
Well just a reference would not cut it.
In English the language that I am not a master of and neither would I
want to be a
master of come what may, there are two words.
Infer
Imply
Both mean more or less the same thing. You say, implied meaning and you say,
I infer from this the following.
Anyway in programming languages references or pointers and the C
language idea of
call by reference and call by value all have something to do with
what I wrote above in
English.
Basically the concept is that in the normal idea in which a variable
holds a value, like
$a = 50;
in the case of a reference or a pointer, you have a certain
associativity as in math like this:
a - b - c
a - (refers to) - b - (refers to) - c
So you say something like this in perl.
$a = 50;
$ref = \$a;
So now it is like this:
$ref - $a - $50
So you can easily dereference $ref and say,
${$ref} and you will get 50.
As you can see a scalar reference is not like a C variable pointer. It
is not that
useful.
What makes us wonder at perl's genius and the cleverness of the design is in
assigning an array pointer.
Like this:
@a = (1,3,4,40);
$aref = \@a;
Now it is fun.
You can do a lot of cool things with it but that will take time. For
now say, you can
do this:
print @{$aref};
And as you can guess you can pass the entire array in one variable by
passing a reference to it.
There are lot of other very useful clever things you can do too.
You can build an array of references.
@refarray = ($aref, $aref2, $aref3);
where,
$aref = [1,3,4,10];
$aref2=[2,3,4,200];
$aref3=[100,girish, 20];
Now you have what can be argued is a 2 dimensional array.
Hmm, things are getting a bit involved no?
Hold on. Be with me.
But before that how do these become array references? I just changed the
() to [] and how do these become references?
That is a perl idiom. Always use funny characters to say what you mean.
So instead of :
@a = (1,3,4);
$ref = \@a;
you say,
$ref = [1,3,4];
Now to dereference you say,
@a = @{$ref};
You can obtain a reference with:
\
and you can dereference with:
@{ }
Try examples.

[Ilugc] [TIP] perl tutorial XII (hashes and references)
References in perl are nothing but pointers but you can't use it like
you do it in C with subtraction, increment and so on.
Perl is a higher level language the references have to be used the perl way.
For instance references allow us to have a hash of arrays. A big array
can be coverted into one element easily with a reference
and you can use that as a value in a hash.
For that matter you can even use function pointers are hash values.
This is in fact a common perl idiom. Of course in perl you
don't call it a function pointer; instead you say subroutine reference.
Anyway now let us look at a hash.
%h = ( 1 = first, 2 = second );
$h{1} is first and $h{2} is second.
Now
%h = ( 1 = [1,2,45,100], 2 = $a);
$a = [1,100,girish];
Of course the second line should come on top of first.
Now you can do like this:
$aref = $h{1};
@arr = @{$aref};
You can build an array of references like this also.
@a = (1,2,3,4, [10,30,4], [1,3,4]);
$a[#a][0], $a[#a][1], $a[#a][2] will give 1,3,4
You can also obtain a reference to a hash.
%hs = ( 123 = 35, 100 = 20);
$ref = \%hs;
%hash = %{$ref};
Now, $hash{123} will give 35.

No, they are not.

Hi, Never mind - they build on top of Amazon EC2 and sell themselves as a platform as a service. They don't sell it as Platform as a Service (which is known as PaaS) but they say that it is Infrastructure as a Service (IaaS). There is lot of difference between the two and of course Amazon has also an offering for PaaS on their IaaS. Right now everybody is offering more of IaaS but may be three to four years down the line, it becomes a commodity item (IaaS) and the real juice lies with PaaS. All the best!
