python批量删除注释_批量删除C和C++注释

使用Python语言 ，实现批量删除C/C++类型注释

1.目前支持去掉.h .hpp .c .cpp .java 这些以//或/**/为注释符的源文件

2.支持递归遍历目录

3.当前版本为Python2.7版本，故只有安装了Python2.7(或Python3.x以下版本的才可以直接使用，测试没问题后将编出exe直接使用)

4.使用方法：

(1)建立源目录，如d:\src(路径中最好不要有中文)；

(2)建立目标目录，如d:\dst(路径中最好不要有中文)；

(3)将RemoveComment.py放到某处(路径中最好不要有中文)，如d:\RemoveComment.py

(4)打开cmd,输入切换到(3)中RemoveComment.py所在的目录(这里是d:\)，输入python RemoveComment.py d:\src d:\dst,回车

(5)去掉了注释的源代码将放在d:\dst目录中
