Perl le用法及代码示例

'乐' 运算符在珀尔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。

用法： String1 le String2

返回：如果左参数小于或等于右参数，则为 1

示例 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

示例 2：字符串 1 等于字符串 2


#!/usr/local/bin/perl 
  
# Initializing Strings 
$a = "Geeks"; 
$b = "Geeks"; 
  
# 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

示例 3：字符串 1 大于字符串 2


#!/usr/local/bin/perl 
  
# Initializing Strings 
$a = "GeeksWelcome"; 
$b = "Geeks"; 
  
# 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：
