Perl | Useful String Operators Last Updated : 21 May, 2021 Comments Improve Suggest changes Like Article Like Report A string in Perl is a scalar variable and start with a ($) sign and it can contain alphabets, numbers, special characters. The string can consist of a single word, a group of words or a multi-line paragraph. The String is defined by the user within a single quote (‘) or double quote (“). Operators are the foundation of any programming language, so as in Perl. A user can define operators in String as symbols that help to perform specific mathematical and logical computations on operands. These operations are like concatenation, comparison, substitution, etc.Example: Perl # Perl program to demonstrate the # Concatenation Operator(.) in String #!/usr/bin/perl # Input first string $first_string = "Geeks"; # Input second string $second_string = "forGeeks"; # Implement Concatenation operator(.) $concat_string = $first_string.$second_string; # displaying concatenation string result print "String After Concatenation = $concat_string\n"; Output: String After Concatenation = GeeksforGeeks Some useful operators for String operations in Perl are listed below: OperatorDescriptionqw'quote word' operator is used to extract each element of the given string as it is in an array of elements in single-quote ( ‘ ‘ )qUsed in place of single quotes.
