Perl le用法及代碼示例

'樂' 運算符在珀爾是用於檢查兩個字符串是否相等的字符串比較運算符之一。它用於檢查其左側的字符串是否小於或等於其右側的字符串。

用法： String1 le String2

返回：如果左參數小於或等於右參數，則為 1

示例 1：String1 小於 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"; 
}

輸出：

String1 is less than or equal to String2

示例 2：字符串 1 等於字符串 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"; 
}

輸出：

String1 is less than or equal to String2

示例 3：字符串 1 大於字符串 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"; 
}

輸出：

String1 is not less than or equal to String2
