This article will explain in detail how to display five random numbers in batch processing. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The code is as follows:

@ echo off

: find 5 different random values in the range of 1-100

:: generate a random sequence R1 between 0 and 99

::

::

::

@ echo off

Setlocal EnableDelayedExpansion

:: initialize sequence sequence

For / l% I in (0mem1mem99) do (

Set rnum%%i=%%i

)

:: random exchange of sequence

For / l% I in (0mem1mem99) do (

Set / a rndflowers random! 100

Call set tmpins%% rnumquota rndbits%%

Set rnum%% I!

Set rnum%% iConstructmp!

)

Set rnum

Pause

Goto: eof

@ echo off

: begin

Cls

Set times=0

Set count=0

: loop

Set / a num=%random%%%99+1

If not defined num%num% (

Set num%num%=%num%

Set / a count+=1

Call echo num%%

)

Set / a times+=1

If% times% equ 20 (

For / l% I in (1mem1mem99) do set num%%i=

Set times=0

)

If count% lss 5 goto loop

Pause > nul

Goto begin

@ echo off

:: Code by JM 2007-1-6 CMD@XP

:: because the structure of echo | find is used, the speed is relatively slow

::

: begin

Cls

Set count=0

: loop

Set / a num=%random%%0+1

Echo str% | find "num%" > nul&&goto loop

Call set str=%%str%% num%

Set / a count+=1

If count% lss 5 goto loop

Echo str%

Set str=

Pause

Goto begin

@ echo off&setlocal enabledelayedexpansion

::

::

For / l% an in (1 * 5) do (

Set/a breadwinner% 99% 1

Call: pp! b!

)

Goto: eof

: pp

If not defined 1 (set 1yoga) else goto loop

Echo 1

Goto: eof

: loop

Set/a breadwinner% 99% 1

Call: pp! b!

@ echo off

Set Max=100

Set Nickel 5

: start

Set Tmp$=

Set / a randomloop= (% random%+%random%+%random%) / 3%%%Max%+1

If Num% LSS 5 goto loop

For / l%% n in (1JI% Num%) do call set / p =% random_%%n%%
