Perl lt运算符

Perl中的’ lt ‘运算符是字符串比较运算符之一，用于检查两个字符串是否相等。它用于检查其左边的字符串是否比其右边的字符串小。

语法： String1 lt String2

返回： 如果左边的参数小于右边的参数，则返回 1。

例1 :

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

输出。

String1 is less than String2

例2 :

#!/usr/local/bin/perl
  
# Initializing Strings
a = "GeeksWelcome";b = "Geeks";
  
# Comparing the strings using lt operator
c =a lt b;
  
if(c == 1)
{
    print"String1 is less than String2";
}
