For with a step in Perl

In Perl, for is used to loop through a list of values. Here's the syntax for using for with a step:

for my $i ($start .. $end step $step) {
    # statements to be executed
}

In the above example, start is the starting point of the loop, end is the ending point of the loop, and step is the increment value for each iteration.

For example, let's say we want to print every other number from 1 to 10. We would use:

for my $i (1 .. 10 step 2) {
    print "$i\n";
}

This would output:

1
3
5
7
9

In another example, let's say we want to add the first 10 even numbers. We would use:

my $sum = 0;
for my $i (2 .. 20 step 2) {
    $sum += $i;
}
print "The sum of the first 10 even numbers is: $sum";

This would output:

The sum of the first 10 even numbers is: 110
