...ted somewhere else. But that could be anywhere, depending on the location selected by the JIT compiler, so the debugger just starts numbering addresses from 0 at the start of the method.

What exactly is a C pointer if not a memory address?
...es after p (assuming p + 1 is still a valid pointer). If q is a pointer to char that points to the same address as p (char *q = p;), then q + 1 is not the same address as p + 1.

What is “Argument-Dependent Lookup” (aka ADL, or “Koenig Lookup”)?
...eems a bit backwards. I would expect the problem do be when std::swap() is selected rather than the overload specific to the type, A::swap(). The example with std::swap(A::MyClass&, A::MyClass&) seems misleading. since std would never have a specific overload for a user type, I don't think i...
