Perl String

Strings are an essential part of the Perl language. They are scalar variables, so they start with ($) sign. A string can be defined within a single quote (‘) or double quote (“).

Perl String Operators

The operators make it easy to manipulate a string in different ways. There are two types of string operators:

• Concatenation (.)
• Repetition (x)

Perl Concatenation Operator

Perl strings are concatenated with a (.) sign instead of (+) sign.

Output:

Output:
