why do you consider that ideal rather than going directly to either cmd or a linux shell?

Here is definition of function taken from an example:
void SettingsDialog::pairingDone(QBluetoothAddress ,QBluetoothLocalDevice::Pairing)
I need to verify the actual address and having a tough time understanding this "syntax".
I do understand that the function parameters are "objects" but when I RTFM it really does not explain the syntax. All I get is "passing by value or by reference" - so what are the parameters actually passed to "pairingDone" ?
If possible
please show me how to get the address - post actual C code
point me to good resource to learn something about the syntax
recommend a C++ book so I can retire my "K&R" book
I can do without opinions and innuendos insults or RTFM replies.

foo(x, y)
int x;
int y;
{
   /* function body */
}

So what is "QBluetoothAddress" - value or reference?

class myClass;
using mc = myClass &;  // mc is a reference to class myClass
// or
using mc = myClass *; // mc is a reference to class myClass
// or
typedef myClass mc;  // mc is a myClass object
// or even
using mc = myClass && // mc is a rvalue reference

I lost my copy of K&R a long time ago. My version was pre-ANSI, which meant that there was no void,

This class holds a Bluetooth address in a platform- and protocol-independent manner.

Here is what I got from Mrs Google example

PLEASE QUIT harassing me about my "lack of basic knowledge" - such continuing (!) harassment just does not fit this forum purpose . ( read how to answer the question INSTRUCTIONS and follow them PLEASE ) I am just learning as I go because I believe that it is better to start with coding a real application and if it does not perform as expected then RTFM and or ask for help.
