Is there a difference between const int with the preceded class qualifier of const (static const int) and const int or is it the same?
If it isn´t equivalent,
Why should I explicitly make a const variable also static?

I think that this means that you have a constant that has a constant address, but I am not sure what this means and want to check.

I understand that the const keyword means that you can't change a variable's value so what does it mean if it used like this :
const char* const& message
The first const stays for the pointer reference itself cannot be changed, so you cannot do something like:
message = &something;
the second const is for the content of the pointer, so you cannot do something like:
*message = something;

This might have been asked and might be a silly question, but what is the difference between these:
void f(int const& par);
void f(const int& par);
There is no difference, const is applied to the left unless it comes first, then it applies to the right.

Which two signatures are equivalent? If none of them are, can you please explain the subtle differences?
The first two are equivalent (the int is const), in the third it's the pointer that's const (i.e. the parameter itself).
