五种酷炫代码⾬的源代码1.脚本篇
@echo off
color 0a
:start
set num=0
set"echos= "
:num
set /a a1=%random%%%3
if"%a1%"=="1"set"a1= "
if"%a1%"=="2"set"a1= "
if"%a1%"=="0"set /a a1=%random%%%2
set echos=%echos%%a1%
set /a num=%num%+1
if"%num%"=="75"echo %echos%&&goto :start
goto :num

使⽤步骤:
1.新建⽂本⽂档，重命名将后⾯的txt改成bat
2.右键选择编辑，进⼊⽂件
3.复制粘贴代码，保存
4.双击打开运⾏
