适配器模式将一个类接口，转换成客户期望的另一个接口，让原本接口不兼容的类可以合作无间。

#ifndef __ADAPTER_H#define __ADAPTER_H#include<iostream>using namespace std;class Duck{public:virtual void quack() = 0;virtual void fly() = 0;};class MallardDuck :public Duck{public:void quack(){cout << "Quack" << endl;}void fly(){cout << "I'm flying" << endl;}};class Turkey{public:virtual void gobble() = 0;virtual void fly() = 0;};class WildTurkey :public Turkey{public:void gobble(){cout << "Gobble gobble" << endl;}void fly(){cout << "I'm flying" << endl;}};class TurkeyAdapter :public Duck{private:Turkey *turkey;public:TurkeyAdapter(Turkey *turkey) :turkey(turkey){}void quack(){turkey->gobble();}void fly(){turkey->fly();}};#endif

#include"adapter.h"void testDuck(Duck* duck){duck->quack();duck->fly();}int main(){MallardDuck* mallarDuck = new MallardDuck();WildTurkey* wildTurkey = new WildTurkey();Duck* turkeyAdapter = new TurkeyAdapter(wildTurkey);cout << "The Turkey says..." << endl;wildTurkey->gobble();wildTurkey->fly();cout << "The Duck says..." << endl;testDuck(mallarDuck);cout << "The TurkeyAdapter says..." << endl;testDuck(turkeyAdapter);}
