Perl Comments

In this tutorial, we will learn how to write comments in Perl programming language. We will go through the different types of comments and how to use them in a program.

What are Comments

Comments in Perl are non-executable statements that are used to annotate the code, provide explanations, and make it more readable. They are ignored by the Perl interpreter during execution.

Syntax

The syntax to define comments in Perl is:

# Single line comment

=pod
Multi-line comment
continues here
=cut

Single line comments

  1. Single line comments in Perl start with # and continue to the end of the line.
  2. They are used to add short explanations or notes within the code.

Perl Program

# Print Hello, World! to the console
print 'Hello, World!';

Output

Hello, World!

Multiline comments

  1. Multiline comments in Perl start with =pod and end with =cut.
  2. They can span multiple lines and are used for longer explanations or to comment out blocks of code.

Perl Program

=pod
Print Hello, World! to the console
This is a multi-line comment
=cut
print 'Hello, World!';

Output

Hello, World!
