一些学习c++的例题

#include <iostream.h>

class S
{
   static int s1;

protected:
   static int s2;

public:
   static int s3;
};

class D : private S
{
public:
   void set()
   {
      S::s1 = 0;
      S::s2 = 1;
      S::s3 = 2;
   }
};

void main()
{
   S objS;
   D objD;

   S::s1 = 0;
   S::s2 = 1;
   S::s3 = 2;

   D::s1 = 0;
   D::s2 = 1;
   D::s3 = 2;

   objS.s1 = 0;
   objS.s2 = 1;
   objS.s3 = 2;

   objD.s1 = 0;
   objD.s2 = 1;
   objD.s3 = 2;
}
