Virtual Functions and Polymorphism
 ```    #include  using namespace std;     class base { public:   virtual void vfunc() {     cout << "This is base's vfunc().\n";   } };     class derived1 : public base { public:   void vfunc() {     cout << "This is derived1's vfunc().\n";   } };     class derived2 : public base { public:   void vfunc() {     cout << "This is derived2's vfunc().\n";   } };     int main() {   base *p, b;   derived1 d1;   derived2 d2;       // point to base   p = &b;   p->vfunc(); // access base's vfunc()       // point to derived1   p = &d1;   p->vfunc(); // access derived1's vfunc()       // point to derived2   p = &d2;   p->vfunc(); // access derived2's vfunc()       return 0; }                ```
