STL标准模板库有六大组件，其中之一就是适配器

六大组件分别是：容器、算法、迭代器、仿函数、空间适配器

适配器可以分为：容器适配器、函数适配器、迭代器适配器

适配器，相当于沟通的桥梁。将一个类的接口转换成用户希望的另一个接口，是不兼容的对象能够互相配合在一起工作，这种模式叫做适配器模式

外国人分为美国人和法国人，他们讲不同的语言，继承一个Foreigner父类，父类有confession()方法返回一个字符串，一个setResult()接受熊猫的回复，子类美国人和法国人需重写confession()方法。

Panda类接收和发送回复。

翻译类。两种语言，子类英语翻译器和法语翻译器继承父类翻译，继承父类构造函数，重写translateToPanda()和translateToHuman()方法，translateToPanda()接收m_foreigner->confession()忏悔并输出， translateToHuman()接收m_panda.sendMessage()回复并输出

#include<iostream>
#include<string>
using namespace std;class Foreigner {
public:virtual string confession() = 0;void setResult(string msg) {cout << "Panda Say: " << msg << endl;}virtual ~Foreigner() {}
};//美国人
class American :public Foreigner {
public:string confession() override {return string("我是畜生, 我有罪!!!");}
};
//法国人
class French :public Foreigner {
public:string confession() override {return string("我是强盗, 我该死!!!");}
};//大熊猫
class Panda {
public:void recvMessage(string msg) {cout << msg << endl;}string sendMessage() {return string("强盗、凶手、罪人是不可能被宽恕和原谅的！");}
};//抽象乔巴翻译适配器类
class AbstractChopper {
public:AbstractChopper(Foreigner* foreigner):m_foreigner(foreigner) {}virtual void translateToPanda() = 0;virtual void translateToHuman() = 0;virtual ~AbstractChopper() {}
protected:Panda m_panda;Foreigner* m_foreigner=nullptr;
};//英语乔巴
class EnglishChopper :AbstractChopper {
public:using AbstractChopper::AbstractChopper;//继承构造函数void translateToPanda() override {string msg = m_foreigner->confession();m_panda.recvMessage("美国人说：" + msg);}void translateToHuman() override {string msg = m_panda.sendMessage();m_foreigner->setResult("美国佬，" + msg);}
};//英语乔巴
class FrechhChopper :AbstractChopper {
public:using AbstractChopper::AbstractChopper;void translateToPanda() override {string msg = m_foreigner->confession();m_panda.recvMessage("法国人说：" + msg);}void translateToHuman() override {string msg = m_panda.sendMessage();m_foreigner->setResult("法国佬，" + msg);}
};
int main() {Foreigner* human = new American;EnglishChopper* american = new EnglishChopper(human);american->translateToPanda();american->translateToHuman();delete human;delete american;return 0;
}
