状态模式

其他二十三种设计模式

#include<iostream>
using namespace std;

//状态模式
class DoWork;

//抽象状态类
class State {
   
   
public:
	virtual void WriteProgram(DoWork* _work) = 0;
};

//添加具体状态类
class ForenoonState :public State {
   
   
public:
	virtual void WriteProgram(DoWork* _work);
};
class NoonState :public State {
   
   
public:
	virtual void WriteProgram(DoWork* _work);
};
class AfternoonState :public State {
   
   
public:
	virtual void WriteProgram(DoWork* _work);
};
class EveningState :public State {
   
   
public:
	virtual void WriteProgram(DoWork* _work);
};
class SleepingState :public State {
   
   
public:
	virtual void WriteProgram(DoWork* _work);
};
class RestState :public State {
   
   
public:
	virtual void WriteProgram(DoWork
