【设计模式】桥接模式

来源：爱编程的大丙

定义：将抽象部分和它的实现部分实现部分分离，使它们可以独立变化，这种处理模式就是桥接模式。

#include<iostream>
#include<map>
#include<string>
using namespace std;//人员信息
struct Person {//使用 string biezhu=string()// 可以让 Person 类的构造函数更灵活，调用者可以选择是否提供 biezhu 参数。Person(string name, string job, string ablity, string reward, string biezhu = string()){this->name = name;this->job = job;this->ability = ability;this->reward = reward;this->beiZhu = biezhu;}~Person() {cout << name << "被析构..." << endl;}string name;    // 名字string job;     // 职责string ability; // 能力string reward;  // 赏金string beiZhu;  // 备注
};//抽象船队
