C++ OJ习题练习(八)设计工人类Worker

Problem Description

设计工人类Worker，它具有姓名name，年龄age，工作部门Dept，工资salary等数据成员。其中，salary为Salary类型的数据，下面的程序拟完成Worker类的设计并用静态成员统计工人的人数，请把程序补充完整。

提示：这里成员函数setXX()用于设置各分项数据，成员函数getXX()用于获取各分项数据，XX代表数据成员，如age对应的成员函数则为setAge()和getAge()。

#include <iostream> #include <string> using namespace std; class Salary{ private: double Wage,Subsidy,Rent,WaterFee,ElecFee;//基本工资Wage，岗位工资Subsidy，房租Rent，水费WaterFee，电费ElecFee public: Salary(double i1,double i2=0,double i3=0,double i4=0,double i5=0){//初始化工资数据的各分项 Wage=i1; Subsidy=i2; Rent=i3; WaterFee=i4; ElecFee=i5; } Salary(){//初始化工资的各分项数据为0 Wage=Subsidy=Rent=WaterFee=ElecFee=0;} void setWage(double f){Wage=f;} double getWage(){return Wage;} void setSubsidy(double f){Subsidy=f;} double getSubsidy(){return Subsidy;} void setRent(double f){Rent=f;} double getRent(){return Rent;} void setWaterFee(double f){WaterFee=f;} double getWaterFee(){return WaterFee;} void setElecFee(double f){ElecFee=f;} double getElecFee(){return ElecFee;} double RealSalary(){//计算实发工资,实发工资=Wage+Subsidy-Rent-WaterFee-ElecFee return Wage+Subsidy-Rent-WaterFee-ElecFee;} }; //你的代码将被嵌在这里 int main(){ Worker w1("John",30,"design"); Worker w2; cout<<"the total num is: "<<w1.getNum()<<endl; w2.setName("Linda"); cout<<"in w2 the name is: "<<w2.getName()<<endl; return 0; }

Sample Output

the total num is: 2 in w2 the name is: Linda

解题代码

class Worker{ static int num; string name,Dept; int age; Salary *salary = new Salary(); public: Worker():age(0),name(""),Dept(""){Worker::num++;} Worker(string n,int i,string dept):age(i),name(n),Dept(dept){Worker::num++;} ~Worker(){Worker::num--;} void setAge(int i) {age = i;} int getAge() {return age;} void setName(string n) {name = n;} string getName() {return name;} void setDept(string dept) {Dept = dept;} string getDept() {return Dept;} void setSalary(double wage) {salary->setWage(wage);} Salary * getSalary() {return salary;} static int getNum(){return Worker::num;} }; int Worker::num = 0;
