Array creation
Hi people,
I am newbie to perl..i have a doubt...
I want to create some 20 arrays using a `for` loop
something like @A1 @A2 @A3....@... this
possible..??
i wrote a code like this for it...
for($i=1;$i++;$i<=20)
{
@A[$i]=`blahblah`;
}
but i was pretty sure it was wrong..(tried executing
it and got an error...)
can this be achieved...?
TIA
Rgds
Harish

Thanks for the concern....

them...by splitting a variable....using `split`.

Let me start with the error you got. I assume you`re using a
standard Perl 5 installation. In this case, assigning a value to an
element of an array, which you tried to do, should be done like this:
$A[$i] = `blahblah`;
If you want to assign values to a 20-element array, do it like this:
foreach $i (0 .. 19) {
$A[$i] = `blahblah`;
}
And if you really want to create 20 arrays in a loop (i strongly
advice you not to do this), this is how it`s done (strict must not
be on):
foreach $i (1 .. 20) {
${`A`.$i}[0] = `blahblah`;
}
With that, you`ll have the arrays @A1, @A2, @A3, ..., @A20 with the
value of their first elements as `blahblah.` However, unless it`s
absolutely necessary, please don`t do this.
You could prolly use double arrays instead.
