VC++串口通信设。本书详细说明讲解了在VC++环境下编写串口通信得过程。值得一看

#include <iostream>
#include <string>

using namespace std ;

class Vegetable
{
public:

   // Pure virtual method makes Vegetable abstract
   virtual string GetColor() = 0;
};


class Broccoli
{
public:

   // Override inherited method as required by abstract base class
   string GetColor();
};

string Broccoli::GetColor()
{
   return "Green";
}


class Cauliflower
{
public:

   // Override inherited method as required by abstract base class
   string GetColor();
};

string Cauliflower::GetColor()
{
   return "White";
}

void main()
{
   Broccoli    MyBroc;
   Cauliflower MyCaul;

   cout << MyBroc.GetColor() << endl;
   cout << MyCaul.GetColor() << endl;
}
