Perl Programming/Simple examples 2

Hi-Lo: A simple game written in perl that asks you for a guess between 1 and 100 and tells you if you are too high or low.

use warnings;
use strict;

$| = 1;

print "Enter number of games to play: ";
chomp(my $Num_Games = <STDIN>);

my $Num_Guesses = 0;
for my $gameno (1 .. $Num_Games) {
	my $number = 1   int rand 100;
	
	my $guess;
	do {
		print "Enter guess from 1 to 100: ";
		chomp($guess = <STDIN>);
		  $Num_Guesses;
		
		if ($guess < $number) {
			print "Higher!\n";
		} elsif ($guess > $number) {
			print "Lower!\n";
		}
	} until $guess == $number;
	
	print "Correct!\nAverage guesses per game: ",
	$Num_Guesses / $gameno, "\n\n";
}

print "Games played: $Num_Games\n";
