Today I finally booked my travel to Brussels next month. In the afternoon I had a refreshing meeting of the faculty council. In the evening it started snowing a bit and thus I designed the following broken code:
namespace n {
class c;
void f(c&);
};
void f(n::c& v) {
f(v);
}
Explain why this is broken code in C++.

Can you elaborate? Am I to assume this is all the code there is, or are some symbols declared elsewhere?
I guess if the f function at the bottom was supposed to be the one at the top, it would be defined in the namespace as well, so I guess the original intention of the code was to call another function also named "f" that lives in a namespace, which will never happen because the current function's scope is matched before the namespace, and thus you have an endless recursion.
You'd have to say n::f(v); for it to call the other function.
This is all the code the compiler is given. It is possible that some declared symbols here are implemented in a different translation unit but this does not make any difference to this question.
It was not supposed that the two mentioned functions are the same. And the problem is not a endless recursion.
And after that your conclusions go more and more to the completely wrong direction.
So sorry, you have to return the cookie from the last question! ;-)
