Pengulangan bertingkat

Kalo di C++ mirip pengulangan bertingkat, di coba deh di kopas di notepad :

@echo off
setlocal ENABLEDELAYEDEXPANSION
:Begin
cls
(set in=)
(set star=)
set /p "in=Input : "
if not defined in goto :Begin
for /l %%a in (1,1,!in!) do (
set "star=*!star!"
echo.!star!
)
pause>nul
goto :Begin
:END
