一些学习c++的例题

#include <iostream>

using namespace std;

class baseClass
{
public:
   baseClass() { cout << "I'm parent.\n"; }
   ~baseClass() { cout << "Parent object has been destructed.\n"; }

   virtual void SayHello() { cout << "Hello!\n"; }
};

class derivedClass : public baseClass
{
public:
   derivedClass() { cout << "I'm child.\n"; }
   ~derivedClass() { cout << "Child object has been destructed.\n"; }

   void SayHello() { cout << "Aloha!\n"; }
};

void main()
{
   baseClass *p = new derivedClass();

   p->SayHello();

   delete p;
}
