Hi,
I'm new to perl and i'm trying to create a simple
program that will act like a time bomb but will print
a dot(something like a progress bar every second until
the specified time arrives. Here's my code.
my $countdown = 5;
while ($countdown > 0){
print "\.";
sleep 1;
$countdown--;
}
print "Kaboom!!"
And the result..
after waiting for 5 seconds, it displayed this line at
once:
.....Kaboom!!
Why does this happens with a while loop? I told it to
print a single dot every 1 second. Do you know another
way of making my progress bar program that display a
single dot every one second on the same line until it
reaches a given time?
Thank you!
