Using C++ for Augmented Reality

Hi, I am new to Unreal Engine and I have a question. Is it possible to use C++ to program my augmented reality apps in UE4, or do I only have the option of using the blueprints to do AR related works ?

As of now, there is only the AR template in the blueprint option.

blueprints are c++ wrapers, you can use this function in the cpp directly.
