Logical Operators in Perl
What are the Logical Operators?
Explanation
The following are the Logical Operators used in Perl.
#! C:programfilesperlbinperl
print "content-type: text/htmlnn";
$a=1;
$b=5;
if( ($a<$b)&&($b>$a))
{
print "Condition is true";
}
else
{
print "Condition is False";
} Result :
Condition is true
In the above example, the variables are compared with two conditions 1<5 and 5>1, so the result would give "Condition is True" as both the conditions are satisfied.
| Operator | Function | |
| && | and | logical conjunction of the two surrounding expressions |
| || | or | logical disjunction of the two surrounding expressions |
| ! | not | returns the logical negation of the expression to its right |
Example :
#! C:programfilesperlbinperl
print "content-type: text/htmlnn";
$a=1;
$b=5;
if( ($a<$b)&&($b>$a))
{
print "Condition is true";
}
else
{
print "Condition is False";
}
Condition is true
In the above example, the variables are compared with two conditions 1<5 and 5>1, so the result would give "Condition is True" as both the conditions are satisfied.
