There is clang format support

how to setup it, I am unable to do it .

https://cpeditor.org/docs/preferences/extensions/#clang-format

getting this error :
[12:00:37] [Formatter] [The format process didn't finish in 2 seconds. This is probably because the Clang Format program is not found by CP Editor. You can set the path to the program at Preferences->Extensions->Code Formatting->Clang Format->Clang Format Program.]

So did you install clang format and add it in PATH?
