The problem is that you're selecting a number at random throughout the range, and you're never adjusting the range. For example, if we were playing the game using 1-100 as the range and you guessed 65 and I said "low", then you'd want to guess a number between 66 and 100. If you then guessed 75 and I said "high", you'd want to guess a number between 66 and 74.

So you need to update the upper or lower limit based on the feedback from the user.

I made it stop guessing zero. I just don't really understand how to set a new minimum or maximum and have it still guess a random number. Updated code below

use strict;
my ($number, $new_guess, $my_hint, @guesses);
my $range = 9;
my $count = 1;
my $number = 1 + int rand 10; #min of 1 and high of 10, range does 0-g
+iven int so i made the range 9 (0-9) and added one to it -> (1-10)
print "My guess is: $number \n";
print "High, low, or right?\n";
while($my_hint ne "right"){
chomp($my_hint = <STDIN>);
@guesses[$count] = $my_hint;
    if ($my_hint eq "low"){
        $new_guess = ((1 + int rand 10);
        print "I guess: " . $new_guess . "\n";
        print "High, low, or right?\n";
    }
    elsif ($my_hint eq "high"){    
        $new_guess = (1 + int rand 10);
        print "I guess: " . $new_guess . "\n";
        print "High, low, or right?\n";
    }
    elsif ($my_hint eq "right"){
        print "It took me " . $count . " tries\n"; 
    }
    else{
        print "What? Am I high, low, or right?\n";
    }    
    $count++;
}

thanks I understand what you are saying. How do you define a range?

randomhero1270:

To select a random number in a particular range:

my $low=65;
my $high=75;
my $guess = int(rand($high-$low+1))+$low;
[download]

Since the range is 65 to 75, there are only 11 choices. So the left part chooses a number from 0 to 10, and then we add the $low end of the range back to turn it into 65 to 75.

Update: as one popular signature goes: Figure out how you'd do it by hand, then program the computer. When you're playing against another person, you don't just guess a random number between 1 and 10 each time, do you? If you did, people would stare at you in puzzlement when you guess 5 they say "high" and then you guess 3. So think about how you do your guessing, and make the computer do it the same way.
