Perl | le 运算符

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

Perl 中的 le 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。它用于检查其左侧的字符串是否小于或等于其右侧的字符串。

语法:string 1lestring 2

如果左参数小于或等于右参数

，则返回: 1

例 1: String1 小于 String2

#!/usr/local/bin/perl

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

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

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

输出:

String1 is less than or equal to String2
