Hi list,

Hope this is not too simple or a stupid question:

I have a slight problem with a loop. It is a simple numbers guessing game. It
works fine, but when I run this script, it gives me "Too low" immediately after
the prompt. What should I do to get the last "else" statement displayed first?

Following is the code:

#!/usr/bin/perl -w


use strict;
use warnings;

$upper = 20 ;
$lower = 1 ;
$target = 11 ;


my $upper = 20;
my $lower = 1;
my $target = 11;

my $guess = <STDIN>;

while ( )
{
if ( $guess > $target )
{
print "Too high\n" ;
$guess = <STDIN> ;
}
elsif ( $guess < $target )
{
print "Too low\n" ;
$guess = <STDIN> ;
}
elsif ( $guess == $target )
{
print "You guessed right\n" ;
exit ;
}
else
{
print "Please choose a number between ${lower} and ${upper}\n" ;
$guess = <STDIN> ;
}
}

Thank you in advance

Danny
