Perl ge用法及代码示例

'葛' 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按字符串方式大于或等于其右侧的字符串。

用法： String1 ge String2

返回：如果左参数大于或等于右参数，则为 1

示例 1：字符串 1 大于字符串 2


#!/usr/local/bin/perl 
  
# Initializing Strings 
$a = "Welcome"; 
$b = "Geeks"; 
  
# Comparing the strings using ge operator 
$c = $a ge $b; 
  
if($c == 1) 
{ 
    print"String1 is greater than or equal to String2"; 
} 
else
{ 
    print"String1 is not greater than or equal to String2"; 
}

输出：

String1 is greater 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 ge operator 
$c = $a ge $b; 
  
if($c == 1) 
{ 
    print"String1 is greater than or equal to String2"; 
} 
else
{ 
    print"String1 is not greater than or equal to String2"; 
}

输出：

String1 is greater than or equal to String2

示例 3：String1 不大于 String2


#!/usr/local/bin/perl 
  
# Initializing Strings 
$a = "Geeks"; 
$b = "GeeksWelcome"; 
  
# Comparing the strings using ge operator 
$c = $a ge $b; 
  
if($c == 1) 
{ 
    print"String1 is greater than or equal to String2"; 
} 
else
{ 
    print"String1 is not greater than or equal to String2"; 
}

输出：

String1 is not greater than or equal to String2
