@APAR1992 骚年，把你写的不行的代码贴出来，很快就能见分晓，比你胡说八道半天要强百倍。

@echo off
title 新建C文件 %date%
pushd "D:\C++\"
Set FileName=%time::=-%.c
echo #include"stdio.h">%FileName%
echo void main()>>%FileName%
echo {>>%FileName%
echo }>>%FileName%
start "" NotePad %FileName%
pause

Rem more +6的6是C程序相对批的起始行
@ echo off
pushd "D:\C++\"
for /l %%a in (1 1 9999) do (
if not exist %%a.c more +6 "%~0">%%a.c&start "" NotePad %%a.c&goto :eof
)
#include"stdio.h"
void main()
