60# liangbch 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

▄︻┻═┳一‥

61# wayne code::blocks 好像不支持命令行编译。

wayne

62# ▄︻┻═┳一‥ 你的意思是说dev-cpp支持命令行。。。。

▄︻┻═┳一‥

63# wayne 恩，你在devcpp的bin目录下可以用cmd 查看 gcc --help

▄︻┻═┳一‥

64# ▄︻┻═┳一‥ 额，你这个不能叫dev-cpp的命令行。。。

5# plp626 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：

1. @echo off
3. setlocal enabledelayedexpansion
5. echo To calculate n^^!
6. set/p nn=n=?
8. set/a "buff_1=1,rad=10000,len=1"
10. for /l %%i in (1,1,%nn% ) do (
11. set/a cc=0
12. for /l %%j in (1,1,!len!) do (
13. set/a "tt=buff_%%j* %%i+!cc!"
14. set/a "buff_%%j=!tt! %% !rad!,cc=!tt!/!rad!"
15. )
16. if !cc! gtr 0 (
17. set/a len+=1
18. set/a buff_!len!=!cc!
19. )
20. )
22. set/p xx=n^^!=<nul
23. set/a tt=buff_%len%
24. set/p xx=!tt!<nul
25. set/a len-=1
27. for /l %%i in (%len%,-1,1 ) do (
28. set/a tt=buff_%%i
29. if !tt! lss 1000 set tt=00000!tt!
30. set/p xx=!tt:~-4!<nul
31. )
33. 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

 A 

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：

1. <pre>
2. typedef struct _ALPC_HANDLE_TABLE // 4 elements, 0x18 bytes (sizeof)
3. {
4. /*0x000*/ struct <a href="ALPC_HANDLE_ENTRY.html">_ALPC_HANDLE_ENTRY</a>* Handles;
5. /*0x008*/ ULONG32 TotalHandles;
6. /*0x00C*/ ULONG32 Flags;
7. /*0x010*/ struct <a href="EX_PUSH_LOCK.html">_EX_PUSH_LOCK</a> Lock; // 7 elements, 0x8 bytes (sizeof)
8. }ALPC_HANDLE_TABLE, *PALPC_HANDLE_TABLE;
9. </pre>

复制代码

变成：

1. typedef struct _ALPC_HANDLE_TABLE // 4 elements, 0x18 bytes (sizeof)
2. {
3. /*0x000*/ struct _ALPC_HANDLE_ENTRY* Handles;
4. /*0x008*/ ULONG32 TotalHandles;
5. /*0x00C*/ ULONG32 Flags;
6. /*0x010*/ struct _EX_PUSH_LOCK Lock; // 7 elements, 0x8 bytes (sizeof)
7. }ALPC_HANDLE_TABLE, *PALPC_HANDLE_TABLE;
