How is C++ used and integrated in systems? Example inside.
Good Evening!
Very new to C/C++, not so much programming. I come from a WebDev background, not a Software Dev/Eng position but I have recently found in interest in learning more about it.
What I was able to gather that C++ is a mid-to-low level language, and is generally used to build GUI based Software/Applications such as .exe programs and games. C is what is used to build Operating Systems and is a lower-level than C++.
But I tend to skip problems #1 and #2 and look directly at problem #150 when I tackle new challenges. Problem #150 is what are Aircraft Avionics Software written in? That is: How does written a program in C++ on board an Aircraft, then tell an on board computer to talk to hardware and say "Lower Landing Gear"?
I'd imagine that C++ program talks to the Operating System (written in C) that has commands (written in C) that were written such that the execute machine language when engages the Landing Gear in a sequence that reads "Lower".
Of course, high-level responses are always welcome, but I work better in learning between the high-to-mid level range right now; not currently at the low-level knowledge of C/C++.
Thank you very much! If more detail is needed to clarify my question, please dont hesitate to ask.
Cheers!

No assignment, just seeking knowledge.
Im an Engineer by trade, but I've always done freelance WebDev (FE and BE) on the side.
Im just curious how C++ can be used to write a .exe which resides on the computer which has an OS written in C (most likely) and somehow say and option on the C++ program to "Lower Landing Gear" actually lowers the landing gear!

It means when a plane is flying...you better lower the landing gear...
Pretty self explanatory...
How does C++ application talk to on board computer OS to talk to the airplanes hardware?

This has something to do with the hardware.
Let's say, a CPU has many PINs (yes, the needles), and each pin has two states: ON and OFF. When it's ON, it's connected, and the current will go through that pin.
So, in a program, it could set the PIN to either ON/OFF to interact with connected hardwares.
For example, we could connect the landing gear's motor to PIN_0 and PIN_1. When PIN_0 is ON, the motor will run, which lowers the landing gear; and when PIN_1 is on, the motor will run in opposite direction, which raises the landing gear.
This is just a very simple example, and of course a plane's landing gear is far more complicated than this, but the idea of controlling hardwares with PIN ON/OFF should be the same.
