Perl | lt 运算符

原文:https://www.geeksforgeeks.org/perl-lt-operator/

Perl 中的 lt 运算符是用于检查两个字符串是否相等的字符串比较运算符之一。它用于检查它左边的字符串是否比它右边的字符串短。

语法: String1 lt String2

如果左参数小于右参数，则返回: 1

例 1:

#!/usr/local/bin/perl

# Initializing Strings
$a = "Geeks";
$b = "Welcome";

# Comparing the strings using lt operator
$c = $a lt $b;

if($c == 1)
{
    print"String1 is less than String2";
}
else
{
    print"String1 is not less than String2";
}

Output:

String1 is less than String2

例 2:

#!/usr/local/bin/perl

# Initializing Strings
$a = "GeeksWelcome";
$b = "Geeks";

# Comparing the strings using lt operator
$c = $a lt $b;

if($c == 1)
{
    print"String1 is less than String2";
}
else
{
    print"String1 is not less than String2";
}

Output:

String1 is not less than String2
