So I read a reference page about this topic while watching the video, and everything was in the reference page is in this video except the new (#elifdef and #elifndef ),
what I'm saying is thank u for the quality content, it helps a lot to build a full picture about different features in the language.

We embedded designers use #define a lot to indicate which microcontroller is being used, for example. If say PIC3215 is used then use the header file of this MCU, else use other header file - this is very powerful feature because it allows us to use the same code for various kinds of microcontrollers without changing the code - pretty smart LOL. Also this helps us a lot in including certain parts of the code, or excluding those parts of the code, based on the customer requirements. This is very powerful feature.
