Consider the following program:
my $me; $me->{verd_result}->[0][2]=5; $me->{verd_result}->[0][5]=34; print "len = ", [EMAIL PROTECTED]>{verd_result}->[0]}}; for (@{$me->{verd_result}->[0]}){ print "\n v="; print; }
How is that related to CGI?
It produces this output:
len = 5 v= v= v=5 v= v= v=34
No, it doesn't. It produces a fatal error.
- Copy and paste code that you post, do not retype it!
- Enable warnings in your program!
How do I modify the program so it only produces this output:
len = 5 v[2]=5 v[5]=34
That output wouldn't be correct, since the array contains six elements, not five.
This code:
my $ref = $me->{verd_result}->[0];
print "len = " . @$ref, "\n";
for ( 0 .. $#$ref ) {
defined $ref->[$_] and print " v[$_]=$ref->[$_]\n";
}outputs: len = 6 v[2]=5 v[5]=34
