mvc模式代码举例

mvc代码实现：
该篇为《mvc 和 mpv 的差别》提供理解帮助

#include 
using namespace std;
#include 

// 抽象层
class Data;
class View;
class Controller;
class Model{
public:
	string name;
	int age;
	virtual void setView(View* v)=0;
	virtual void update()=0;
	virtual void setData(Data* d)=0;
};
class View{
public:
	virtual void setController(Controller* c)=0;
	virtual void userRequest()=0;
	virtual void showData(Model* m)=0;
};
class Controller{
public:
	virtual void setModel(Model* m)=0;
	virtual void requestData()=0;
};
//具体层
class Data{
public:
	Data(string n,int a){
		name = n;
		age =a;
	}
	string name;
	int age;	
};
class ConcreteModel: public Model{
public:
	View* mv;
	virtual void setView(View* v){
		mv = v;		
	}
	virtual void update(){
		mv->showData(this);		
	}
	virtual void setData(Data* d){
		name = d->name;
		age = d->age;
		update();
	}
};
class ConcreteView: public View{
public:
	Controller* mc;
	virtual void setController(Controller* c){
		mc = c;
	}
	virtual void showData(Model* m){
		cout<<"name:"<<m->name<<"\n";	
		cout<<"age:"<<m->age<<"\n";
	}
	virtual void userRequest(){
		mc->requestData();		
	}
};
class ConcreteController:public Controller{
public:
	Model* mm;
	virtual void setModel(Model* m){
		mm = m;	
	}
	virtual void requestData(){
		Data* data = new Data("xiao ming", 5); 
		mm->setData(data);
	}
};
//客户端调用
int main()
{
	cout<<"mvc模式\n";
	Model* m = new ConcreteModel();
	View* v = new ConcreteView();
	Controller* c = new ConcreteController();
	m->setView(v);
	v->setController(c);
	c->setModel(m);
	v->userRequest();


	//看代码不用考虑以下内容
	int cin_a;
	cin>>cin_a;
	return 0;
}
