The operator associates the string with the regexp match and produces a true value if the regexp matched, or false if the regexp did not match.

next – learns how to control the flow of the loop. World is the regular expression and the // enclosing /World/ tells Perl to search a string for a match.do…until – execute a block of code repeatedly with the test condition checked at the end of each iteration.until – learns how to execute a block of code as long as a condition is true.
do…while – learns how to execute a block of code as long as the. while – shows you how to execute a block of code based on a condition. for loop – learns how to iterate over elements of a list. Perl comparison operators can sometimes be confusing to new Perl programmers. b string operator prints 2 plus the three or 23 print ab arithmetic operator prints 6. given…when – introduces the given…when statement that allows you to match a value or variable against a list of values. Perl has its own addition and mulitply operators for strings. unless – provides you with another statement to execute a block of code based on a condition. if…else – learns how to use the if…else statement to execute a block of code based on a specified condition. In addition, you’ll learn how to use a relatively new statement in Perl called given/when statement, which is similar to the switch case statement in C. In Perl, operators symbols will be different for different kind of operands (like scalars and string). An operator is a character that represents an action, for example + is an arithmetic operator that represents addition. 
In this section, you’ll learn how to use Perl control flow statements including if/elsif/else, for/foreach, while/do while, until/do until, next,last statements. Operators allow the programmer to perform different kinds of operations on operands.
