Lookup rule

Given a program as simple as

class A{void func();}
class Bublic A{void func();}
class Cublic B,A{void func();}


// call it
C p;
p.func();

How can a compiler determine which function is called ? Thank you.

The most-derived class (C)'s function will be used in this case.

If C didn't have a func(), then B's would be used.

If C did have a func() but it had a different parameter list, then by default a compile error would result, but a "using B::func" statement in the class definition would allow B's func() to be used.

Besides, if your base class is virtual, it will use the virtual class first before checking itself.

Eo`eo' eo, unclear enough to qualify your reply. It applies the bottom up approach as a rule (child->parent->grandparent etc)
