C++ & blueprint

I’m new to the unreal engine and I’m about to start my first project. I am not sure whether to make a project with c++ or blueprint.
If i select one will I be able to us the other during the production of my game?
I have listed a picture below if you are unsure of what I mean.

Yes, Blueprints and C++ code can be created regardless of the language you want your initial assets to be generated.

Inside the editor, you can Create a New Blueprint or Create a New C++ Class.
