Dear Monks,
I've just stumbled over a small issue with chomp/split (or just my understanding of them). Here's the code to test:
#!/usr/bin/perl
use strict;
use warnings;
my $line ="A\tB\tC\tD\t\t\t\t\n";
print "Test string line: $line";
print "Split without chomp: ";
count_fields( $line );
print "Split _after_ chomp: ";
chomp $line;
count_fields( $line );
exit;
sub count_fields {
my ($line) = @_;
my @x = split( /\t/, $line);
my $count = @x;
print "$count fields.\n";
}
I expected to print out the same field count - 8 - regardless of applying or not the 'chomp'. Instead, I see 8 and 4. Can someone shed some lite on it ? Why do the two field counts differ ..?!!
Many thanks,
