Re3: Use an array slices

I assume that case would look something like this:

#!/usr/bin/perl -wT
use strict;

my $value = 10;

SWITCH: for ($value) {
    /0/  && do {print "ZERO\n"; last; };
    /1/  && do {print "ONE\n";  last; };
    /10/ && do {print "TEN\n";  last; };
                print "NONE OF THE ABOVE\n";
}

Can you guess what the output is? Run it and find out.

It produces the ZERO message :) Matching the whole string produces better results: `#!/usr/local/bin/perl use strict; use warnings; my $value = 10; SWITCH: for ($value) { /^0\z/ && do {print "ZERO\n"; last; }; /^1\z/ && do {print "ONE\n"; last; }; /^10\z/ && do {print "TEN\n"; last; }; print "NONE OF THE ABOVE\n"; }` [download]	[reply] [d/l]

Well, "ZERO". But that's easily solvable (although it looks less pretty): `#!/usr/bin/perl -wT use strict; my $value = 10; SWITCH: for ($value) { /^0$/ && do {print "ZERO\n"; last; }; /^1$/ && do {print "ONE\n"; last; }; /^10$/ && do {print "TEN\n"; last; }; print "NONE OF THE ABOVE\n"; }` [download] Leonid Mamtchenkov	[reply] [d/l]
