Could you please give me some more help on this tr/// statement?
Could you please tell me if there is any improvement I should do? I use something like this:
@letter = qw( a b c w x y );
for ($n=0; $n<6; $n++){
$x = $letter[$n];
$m = 0;
open (DATA, "data.txt") ||
die "Could not open source data file.";
while (<DATA>) {
$cnt = eval "tr/$x/$x/";
$m += $cnt;
}
print "$x $m";
}
data.txt contains lines like:
aedj dfas jijiojsdf dsfwfy jiox jiohjdfax jojojdjj, oiiia oioje asfdc oujsdfayx soujfosdxjpoiojfdxjljojaois jojojx jopjpx jojoijx joijiodfx
