继承与派生的关键应用，和基础用法 #include <iostream> using namespace std; class employee{ public: employee(int g){grade=g;} double pay(); protected: int grade; double accumPay; }; double employee::pay() { accumPay=30*grade; cout<<"基本月薪："<<accumPay<<endl; return accumPay; } class worker:public employee{ public: worker(int a,int t):employee(a){time=t;} void payworker(); private: double time; }; void worker::payworker() { accumPay=pay()+100*time; cout<<"工人人员月薪总额:"<<accumPay<<endl; } class salesman:public employee{ public: salesman(int b,int t,double s):employee(b){time=t,sale=s;} void paysalesman(); private: double sale,time; }; void salesman::paysalesman() { accumPay=pay()+100*time+sale*0.01; cout<<"推销人员月薪总额:"<<accumPay<<endl; } class manager:public employee{ public: manager(int c):employee(c){} void paymanager(); }; void manager::paymanager() { accumPay=pay()+8000; cout<<"管理人员月薪总额"<<accumPay<<endl; }
