很好奇?

.bat 的排序程式要如何撰寫?

哈, 牛皮吹破了 ^_^

硬著頭皮寫了個四個值的排序給大家笑一笑

執行方式：swap 8 9 20 34
先將以下的程式碼存成 swap.bat
@ECHO OFF
SET N1=%1%
SET N2=%2%
SET N3=%3%
SET N4=%4%

ECHO ORIGIN:%n1% %N2% %N3% %N4%

IF %N1% GTR %N2% GOTO SWAPN1N2
:NEXT01
IF %N1% GTR %N3% GOTO SWAPN1N3
:NEXT02
IF %N1% GTR %N4% GOTO SWAPN1N4
:NEXT03
IF %N2% GTR %N3% GOTO SWAPN2N3
:NEXT04
IF %N2% GTR %N4% GOTO SWAPN2N4
:NEXT05
IF %N3% GTR %N4% GOTO SWAPN3N4
:NEXT06

ECHO SORTED:%n1% %N2% %N3% %N4%

GOTO STOP

:SWAPN1N2
SET TEMP=%N1%
SET N1=%N2%
SET N2=%TEMP%
GOTO NEXT01

:SWAPN1N3
SET TEMP=%N1%
SET N1=%N3%
SET N3=%TEMP%
GOTO NEXT02

:SWAPN1N4
SET TEMP=%N1%
SET N1=%N4%
SET N4=%TEMP%
GOTO NEXT03

:SWAPN2N3
SET TEMP=%N2%
SET N2=%N3%
SET N3=%TEMP%
GOTO NEXT04

:SWAPN2N4
SET TEMP=%N2%
SET N2=%N4%
SET N4=%TEMP%
GOTO NEXT05

:SWAPN3N4
SET TEMP=%N3%
SET N3=%N4%
SET N4=%TEMP%
GOTO NEXT06

:STOP

其實，批次檔就用sort就可以排序啦！這樣應該不算作弊啦！
用pipeline，把資料倒入sort就可以排序。
只是這樣不算寫程式就是。
