设计模式依赖倒转原则

让每个类都遵循单一职责原则

// 依赖倒转原则.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include 
using namespace std;
class AbstractWorker{
public:
	virtual void doBussiness()=0;
};
class SaveBankWorker:public AbstractWorker{
public:
	virtual void doBussiness(){
		printf("办理存款业务n");
}
};
class PayBankWorker:public AbstractWorker{
public:
	virtual void doBussiness(){
		printf("办理支付业务n");
}
};
class TransBankWorker:public AbstractWorker{
public:
	virtual void doBussiness(){
		printf("办理转账业务n");
}
};
//要存在一个中层业务
void doNewBusiness(AbstractWorker *worker)
{
	worker->doBussiness();
}
void test01()
{
	AbstractWorker *worker=new TransBankWorker;
	worker->doBussiness();
	delete worker;
	worker=new PayBankWorker;
	worker->doBussiness();
}
int main(int argc, char* argv[])
{
	test01();
	printf("Hello World!n");
	return 0;
}
