You must pass the additional arguments on the command line when executing the program.
When using a command shell type:
/path64/debug/facedetece.exe </path/to/haar_cascade> </path/to/csv.ext> </path/to/device id>
replacing the argument place holders with your actual pathes and file names.
When using some kind of IDE (C++ development environment), check the documentation of that on how to specify these arguments in the project settings to be passed when starting the application from within the IDE.
