i see, therefore references in C++ or pointer in C++ or C are both "pass by
reference". Is it not the same semantic and only a different syntax?
To be aware of the side effect if you write
void foo(int &a) {...
a = b;
}
The point of Dieter, because he dislikes references, is that with pointer syntax
the side effect is obvious.
