dev-cpp 连续六年没有更新，自然GCC也是很老很老的。
====================
用dev-cpp 还不如用code::blocks

61# wayne

code::blocks 好像不支持命令行编译。

你的意思是说dev-cpp支持命令行。。。。

恩，你在devcpp的bin目录下可以用cmd 查看 gcc --help

Options starting with -g, -f, -m, -O, -W, or --param are automatically
passed on to the various sub-processes invoked by gcc. In order to pass
other options on to these processes the -W<letter> options must be used.

额，你这个不能叫dev-cpp的命令行。。。

这样的命令才差不多，呵呵，个人感觉。

奉上我的批处理习作。我的第一个用于数值计算的批处理程序。这个程序可计算n的阶乘。n>=1, 代码如下：

@echo off
setlocal enabledelayedexpansion
echo To calculate n^^!
set/p nn=n=?
set/a "buff_1=1,rad=10000,len=1"
for /l %%i in (1,1,%nn% ) do (
set/a cc=0
for /l %%j in (1,1,!len!) do (
set/a "tt=buff_%%j* %%i+!cc!"
set/a "buff_%%j=!tt! %% !rad!,cc=!tt!/!rad!"
)
if !cc! gtr 0 (
set/a len+=1
set/a buff_!len!=!cc!
)
)
set/p xx=n^^!=<nul
set/a tt=buff_%len%
set/p xx=!tt!<nul
set/a len-=1
for /l %%i in (%len%,-1,1 ) do (
set/a tt=buff_%%i
if !tt! lss 1000 set tt=00000!tt!
set/p xx=!tt:~-4!<nul
)
echo.

向上面的两位求助。
有个提取文本，想用批处理完成。
有多个*.html 文件，要求提取出 <pre> A </pre> 之间的c 数据结构A.

A中有<>也要去掉，得到的c语言数据结构A保存到同一个文本文件中。
比如：

<pre>
typedef struct _ALPC_HANDLE_TABLE // 4 elements, 0x18 bytes (sizeof)
{
/*0x000*/ struct <a href="ALPC_HANDLE_ENTRY.html">_ALPC_HANDLE_ENTRY</a>* Handles;
/*0x008*/ ULONG32 TotalHandles;
/*0x00C*/ ULONG32 Flags;
/*0x010*/ struct <a href="EX_PUSH_LOCK.html">_EX_PUSH_LOCK</a> Lock; // 7 elements, 0x8 bytes (sizeof)
}ALPC_HANDLE_TABLE, *PALPC_HANDLE_TABLE;
</pre>

复制代码

变成：

typedef struct _ALPC_HANDLE_TABLE // 4 elements, 0x18 bytes (sizeof)
{
/*0x000*/ struct _ALPC_HANDLE_ENTRY* Handles;
/*0x008*/ ULONG32 TotalHandles;
/*0x00C*/ ULONG32 Flags;
/*0x010*/ struct _EX_PUSH_LOCK Lock; // 7 elements, 0x8 bytes (sizeof)
}ALPC_HANDLE_TABLE, *PALPC_HANDLE_TABLE;
