anniyan has asked for the wisdom of the Perl Monks concerning the following question:
Monks, I have one question realated to translation.
I have read the following from an online material.
The c option (c is for "complement") translates all characters that are not specified. For example, the statement $string =~ tr/\d/ /c; replaces everything that is not a digit with a space.
But when i tried the following i am getting the following output than what i expected.
$a = 'acvdef431234'; $a =~ tr/\d/ /c; print "$a"; output: d expected output: 431234
But if i used [0-9] it is working good.
$a = 'acvdef431234'; $a =~ tr/[0-9]/ /c; print "$a"; output: 431234
I am in total confusion. Could anyone explain whats going on there.
Regards,
Anniyan
