# What are the logical operators and, or, & not in Perl?

harris910

A logical operator is a symbol or word that connects two or more expressions so that the value of the created expression is solely determined by the value of the original expressions and the operator’s meaning.

Below are the logical operators available in Perl:

• and
• or
• not

### Description

The table below explains each of the logical operators in Perl.

 Operator Symbol Operator Name Example Description &&and Logical And Operand-A && Operand-B Returns True when both operand-A and operand-B are True; otherwise, it returns False. ||or Logical Or Operand-A || Operand-B Returns True when either operand-A or operand-B is True; otherwise, it returns False. not Logical Not not Operand-A Returns the operand's logical state in reverse.

The figure below is the visual representation of the logical operators in Perl.

Note:

• True equates to 1.
• False equates to nothing.

### Code

The following code demonstrates how to use these logical operators in Perl.


$A=10,$B=20, $C=30; #And Operator #Both True print "The value of (A<B && B<C): ".($A<$B &&$B<$C). "\n"; #First operand: True Second Operand: False print "The value of (A<B and B>C): ".($A<$B and$B>$C). "\n"; #Both False print "The value of (A>B && B>C): ".($A>$B &&$B>$C). "\n"; #Or Operator #Both True print "The value of (A<B || B<C): ".($A<$B ||$B<$C). "\n"; #First operand: True Second Operand: False print "The value of (A<B or B>C): ".($A<$B or$B>$C). "\n"; #Both False print "The value of (A>B || B>C): ".($A>$B ||$B>$C). "\n"; #Not operator$D=1;
#reverse of true logical state
print "The value of not(D): ".not(\$D). "\n";
