Perl | Useful String Operators

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 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"; 

String After Concatenation = GeeksforGeeks
