刚开始学，写的比较中规中矩，，看了几页帖子，发现代码还可以精简；还有很多用for循环的写法，思路真不错，学习了。

我是小白

@echo off
set str1=今日明月在
set str2=%str1:~0,2%
set str3=%str1:~2,2%
set str4=%str1:~-1%
echo %str2%
echo %str3%
echo %str4%
echo %str3%%str2%%str4%
pause
复制代码

我这比较笨的方法。运行会浪费资源。

::有一个 QQ 昵称为“今日明月在”，（昵称是不是很诗意呢？）
::1、请分别截取“今日”、“明月”、“在”，并显示出来。
::2、通过变量截取把 “今日明月在” 变成 “明月今日在” 显示出来。
