In Perl, next and continue are control statements used in loop constructs.
next statement is used to skip to the next iteration of the loop immediately. Here is an example of using next in a for loop to print only odd numbers:
for my $num (1..10) {
if($num % 2 == 0) { # if the number is even
next; # skip to the next iteration immediately without printing
}
print $num."\n";
}
In this example, next is used to skip printing even numbers and proceeding to the next iteration of the loop.
continue statement is used to skip to the next iteration of the loop after executing the current iteration. Here is an example of using continue in a while loop to print only odd numbers:
my $num = 1;
while($num <= 10) {
if($num % 2 == 0) { # if the number is even
$num++;
next; # skip to the next iteration after incrementing the number
}
print $num."\n";
$num++;
continue; # skip to the next iteration after incrementing the number
}
In this example, continue is used to skip to the next iteration after printing odd numbers and incrementing the value of the loop variable $num.
