array instance in another array

[alanchia]

hi all,

can i do this ?

@testing=<MYFILES>;
@contents = qw($testing[5]);

if not how do i go about doing that ?

thanks

You can't do that because qw() doesn't do variable interpolation. So you would would get the literal string '$testing[5]' and not the 6th element of the @testing array. Just get rid of the qw.

@contents = ( $testing[5] );
# Or even
push @contents, $testing[5];

jaa

thanks,

but what if my testing[5] is a sentence with whitespaces in between and i want each word to be an instance of @contents ? e.g

print $testing[5]; would give &quot; i am a boy&quot;

and i want

print contents[0]; to give &quot; i &quot;
print contents[1]; to give &quot; am &quot;
and so forth..

thanks

something like:

@contents = split $testing[5];

I think should do it. I think that split splits on whitespace by default.

Split only defaults to whitespace when it defaults to $_. i.e. you can only leave off the pattern if you are splitting $_ and split has no other arguments, otherwise you have to include the pattern.

$_ = 'i am a boy';
@contents = split;
# or
@contents = split /\s+/, $_;
# or even
@contents = split /\s+/;
# but not
@contents = split $_;

The pattern must be the first or only argument.
So the pattern is necessary in the above example.

my @contents = split /\s+/, $testing[5];

jaa
