Counting (easy!) (YES!!)

[Trent Rigsbee]

I think I figured it out! A FIRST!!

for ($i = 1; $i <= 5; $i++){
sleep 1;
print "$i\n";
}


I prints out like this: 1...2...3...4...5

YES!!

Thanks everyone! :-)

As you move into larger programs and scripts it
is a good idea to always use strict and warnings.

use strict;
use warnings;

After adding these to the top of your script
you'll need to use 'my' before using most variables
for the first time:

use strict;
use warnings;

for ( my $i; $i <= 5; $i++ ) {
sleep 1;
print "$i\n";
}


You can also use the range operator to save some
typing:

for my $i ( 1 .. 5 ) {
sleep 1;
print "$i\n";
}
