Perl | ne operator

Last Updated : 07 May, 2019

‘ne‘ operator in Perl is one of the string comparison operators used to check for the equality of the two strings. It is used to check if the string to its left is stringwise not equal to the string to its right.

Syntax: String1 ne String2
Returns: 1 if left argument is not equal to the right argument

Example 1:

#!/usr/local/bin/perl
  
# Initializing Strings
$a = "Welcome";
$b = "Geeks";
  
# Comparing the strings using ne operator
$c = $a ne $b;
  
if($c == 1)
{
    print"String1 is not equal to String2";
}
else
{
    print"String1 is equal to String2";
}

Output:

String1 is not equal to String2

Example 2:

#!/usr/local/bin/perl
  
# Initializing Strings
$a = "Geeks";
$b = "Geeks";
  
# Comparing the strings using ne operator
$c = $a ne $b;
  
if($c == 1)
{
    print"String1 is not equal to String2";
}
else
{
    print"String1 is equal to String2";
}

Output:

String1 is equal to String2
