Question

C++ provides a syntax for checked exceptions, for example:

void G() throw(Exception);
void f() throw();

However, the Visual C++ compiler do

Answer 1

Exception specifications are pretty useless in C++.

It's not enforced that no other exceptions will be thrown, but merely that the global function unexpected() will be called (which can be set)

Using exception specifications mainly boils down to deluding yourself (or your peers) into some false sense of security. Better to simply not bother.
