But after installong the zip file I am unable to get the main.cpp file. Please help me with this issue
What do you mean that you were “unable to get the main.cpp?” main.cpp does no come with the C++ library when you download it from Edge Impulse. You need to create it yourself, as it is that main part of your application.
What documentation are you following? Can you share your Edge Impulse project ID?
