编写一个C++程序, 计算程序员( programmer )工资
1 要求能计算出 初级程序员( junior_programmer ) 中级程序员 ( mid_programmer ) 高级程序员( adv_programmer)的工资 2 要求利用抽象类统一界面,方便程序的扩展, 比如:新增, 计算 架构师 (architect ) 的工资C++中没有Java中的接口概念，抽象类可以模拟Java中的接口类。（接口和协议）
下面程序定义一个程序员的类，里面有纯虚函数。
#includeusing namespace std;class programmer{public: virtual void getSal() = 0;};//初级程序员class junior_programmer :public programmer{public: junior_programmer(char *name,char *job,int sal) { this->name = name; this->job = job; this->sal = sal; } virtual void getSal() { cout << name << " " << job << " : " << sal << endl; }private: char *name; char *job; int sal;};//中级程序员class mid_programmer :public programmer{public: mid_programmer(char *name, char *job, int sal) { this->name = name; this->job = job; this->sal = sal; } virtual void getSal() { cout << name << " " << job << " : " << sal << endl; }private: char *name; char *job; int sal;};//高级程序员class adv_programmer :public programmer{public: adv_programmer(char *name, char *job, int sal) { this->name = name; this->job = job; this->sal = sal; } virtual void getSal() { cout << name << " " << job << " : " << sal << endl; }private: char *name; char *job; int sal;};//架构师class architect :public programmer{public: architect(char *name, char *job, int sal) { this->name = name; this->job = job; this->sal = sal; } virtual void getSal() { cout << name << " " << job << " : " << sal << endl; }private: char *name; char *job; int sal;};//计算工资，简单的框架void call_programer_sal(programmer *base){ base->getSal();}int main(){ junior_programmer jp("小赵", "初级程序员", 4000); mid_programmer mp("小钱", "中级程序员", 8000); adv_programmer ap("小王", "高级程序员", 12000); //系统扩展 architect arch_pro("小周", "架构师", 16000); call_programer_sal(&jp); call_programer_sal(&mp); call_programer_sal(&ap); call_programer_sal(&arch_pro); return 0;}
