vscode 自动修改C代码格式

1.插件clang-format安装

 clang-format默认安装路径为c:\Users\wqr57\.vscode\extensions\ms-vscode.cpptools-0.18.1/bin/../LLVM/bin/clang-format.exe

 

2.C 格式客制化配置

3.问题

 客制化的.clang-format 没有生效

 (1).clang-formt 没生效

 设只快捷键格式化生效：CTRL+s

 2.修改.clang-format 文件，ctrl+s c文件格式化没生效

（1）.clang-format 里添加了中文注释

 （2）如下设置【Clang-format:Style : file】clang-format.exe 默认会从当前目录或父目录查找.clang-format文件，当然你如果不想放入项目代码的目录中可以选择.clang-format的绝对路径，如下
