* C VS C++
* new expression
-operator new, new_hanlder
* Polymorphism
-virtual function
-is this program compile right? run right?
class A{
public: virtual void foo(){}
};
class B:public A{};
int main(){
B b;
b.foo();
}
[我开始说2个都是right，他连问3次"Are you sure?";第三次问的时候，我改了说，compile right, run wrong。但是，后面越想越不对，我返回去说这道题目，2个都是right，很sure]
-how is virtual table is constructed
-running time, how can a call to find the right virtual function
-下面这个设计有啥不好
class A{
public: virtual void foo(){}
virtual void foo
