Perl continue Statement

Perl Loops

The Perl continue block is typically executed before the condition is re-evaluated.

The continue statement can be used in while and foreach loops.

Syntax

The syntax for the continue statement in a while loop is as follows:

while(condition){
   statement(s);
}continue{
   statement(s);
}

The syntax for the continue statement in a foreach loop is as follows:

foreach $a (@listA){
   statement(s);
}continue{
   statement(s);
}

Example

Using the continue statement in a while loop:

Example

#/usr/bin/perl

$a = 0;
while($a < 3){
   print "a = $a\n";
}continue{
   $a = $a + 1;
}

Executing the above program will produce the following output:

a = 0
a = 1
a = 2

Using the continue statement in a foreach loop:

Example

#/usr/bin/perl

@list = (1, 2, 3, 4, 5);
foreach $a (@list){
   print "a = $a\n";
}continue{
   last if $a == 4;
}

Executing the above program will produce the following output:

a = 1
a = 2
a = 3
a = 4
