我也借用12楼，rat的代码写写：

@echo off
set/a num=%random%
2>nul set/a1/(%num%%%2)&&echo %num% 是奇数||echo %num% 是偶数
pause>nul
复制代码

@echo off
setlocal enabledelayedexpansion
set var=%random%
set num=
for /f "delims=13579" %%i in ("!var:~-1!") do set num=%%i
if not defined num (echo !var!是奇数) else (echo !var!是偶数)
pause>nul
复制代码
