What's the difference between address and pointer?

here is the link that has the sentenses in which i have some questions.

https://kr.mathworks.com/help/ecoder/ref/passreusablesubsystemoutputsas.html?searchHighlight=Pass%20reusable%20subsystem%20outputs%20as%20individual%20arguments&s_tid=srchtitle_Pass%20reusable%20subsystem%20outputs%20as%20individual%20arguments_2

and this doc says " Passes each reusable subsystem output argument as an address of a local, instead of as a pointer to an area of global memory containing the output arguments."

1. what's the difference between address and pointer. Are they samething?
2. what's the reusable subsystem? -> I guessed being good at reuseing to any other model. is that right?
3. what's the global memory?
4. what's the argument?

Hello Min Hoon

Code generation in Simulink provides code optimization by allowing function reuse. The following documentation link guides you through the ways to function reuse. Kindly go through it. Function Reuse in Generated Code - MATLAB & Simulink - MathWorks India

Function subsystems can be reused, and passed as structure or argument in the code generated. The documentation link shows how the two generated codes differ Optimize Generated Code by Passing Reusable Subsystem Outputs as Individual Arguments - MATLAB & Simulink - MathWorks India

You may find the answer to your queries in the above documentation links
