Global reference to global objects

I have some immutable global objects like so:

const Vehicle Car   = ...;
const Vehicle Truck = ...;
...

I need to make "aliases" to these objects, i.e., additional names which refer to the same object.

This seems to work:

const Vehicle& Camion = Truck;

Is it allowed and will it blow up in my face somehow? Will using Camion be the same as using Truck, including the object address?

Yes, this is fine.

Reference declaration

Declares a named variable as a reference, that is, an alias to an already-existing object or function.

This is what references are for. They are essentially another name for the same thing. And yes, taking address of a reference gives you the address of the actual variable it is referencing.

Yes, you it will be same because the same variable points the same memory address and change in memory address can effect both the variable. https://www.youtube.com/watch?v=Zl-JLUOuyGI
