To print an Hourglass Pattern in Perl, we use nested loops. The outer loop controls the rows, and the inner loops control the spaces and stars (*) to form the pattern.
In this example,
print_hourglass
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from n
to 1 and the inner loops control the spaces and stars in each row.sub print_hourglass {
my ($n) = @_;
for my $i (reverse 1 .. $n) {
print ' ' x ($n - $i), '*' x (2 * $i - 1), "\n";
}
for my $i (2 .. $n) {
print ' ' x ($n - $i), '*' x (2 * $i - 1), "\n";
}
}
# Example usage
print_hourglass(5);
