Here's a fixed version, not much though into it, you can figure out how
to remove the trailing ,
$source_file = "input.txt";
$result_file = "output.txt";
open (SOURCE, $source_file) || die "cannot open $source_file: $!";
open (RESULT, ">$result_file") || die "cannot open $result_file: $!";
while (<SOURCE>)
{
chomp; #Delete the NL character
# If you don't want the quotation marks in your output remove the \"
from the next line
print RESULT "\"$_\","; # You opened the RESULTS file but did not
write to it...
}
close SOURCE; # Just make sure you close files after you are done with
them...
close RESULT;
