C++ 的恐怖

Linux之父曾说过C++是很恐怖的。开始还不相信但看到下面的程序时，我就相信了。

 

class A{public:void f() {cout<<"a"<<endl;}void p() {u = 100;cout << u<<endl;}int u;};class B:public A{public:void c() {cout << "c"<<endl;}void f() {i = 10;cc = 2;cout<<"b"<<endl;}void g() {cout << i << " " << cc <<endl;}public:int i;int cc;};int main(){A *pa=new A();B* pb=(B*)pa;pb->p();pb->f();pb->g();system("pause");return 0;}
