怎么样去除C++注释的脚本？
怎么样去除C++注释的脚本？
'
' 去除CPP注释.vbs
' 2006/11/16
' Yi Wang
'
' Ver3.0.0
' 能够区分""中的注释符号。除了多行字符串:
' "a multi-line /
' String literal signals its /
' continuation with a backslash."
'
' 用法：
' 将需要处理的文件托拽到该脚本上。
'
' 注意：
' 使用脚本之前请先备份源代码文件!!!
' 脚本长时间没有响应，到任务管理器中关闭WScript.exe进程，结束脚本执行。
' 作者不为使用脚本造成的任何损失负责。
'
' 修改记录：
' 2.0.2 (1) 修改处理"/*//"类似代码时，搜索起点的BUG。
' (2) 报告错误信息时添加文件名。
' 3.0.0 (1) 添加递归文件夹的功能
' (2) 添加识别文件后缀名的功能，能识别的后缀名：H,C,CPP,CXX,INC,JAVA
' (3) 报告结果由没处理一个文件之后，改到所有都处理完毕之后。
' (4) 报告结果写入同时生成的日志中。
