 Posted: Sun Aug 24, 2008 11:01 pm Post subject: Perl - Testing user input for specific values [SOLVED] |
 |
|
Hello... I am a newbee @ perl and LOVING IT!!! I need to ask a user a question and give them two choices. If neither is chosen, ask again until one of the valid choices is input. What is the most logical/cleanest way to do this?
Any help is much appreciated!

| Code: | while (<STDIN>) {
chomp;
if ($_ eq "Door number 1") {
print "You win: a potted plant.\n";
last;
}
if ($_ eq "Door number 2") {
print "You win: a gas guzzling pickup truck.\n";
last;
}
print "Sorry, you must choose a door.\n";
}
# At this point, either the user gave up and quit or the user picked one
# of the two doors.
