Perl lt用法及代碼示例

'其' 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其右側的字符串。

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

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

輸出：

String1 is less than String2

示例 2：


#!/usr/local/bin/perl
