c++工资管理系统

用类的方法

描述：

根据是否为经理和普通职员发工资

如果是经理，则工资为10000加上入职时间乘以5000

反之则为2000加上入职时间 乘以200

代码如下：

//SalarySystem.h

#pragma once

#include <string>
#include <iostream>

using namespace std;

const int MAX_COUNT = 1000;

// 员工类即基类
class Emplyee
{
public:
Emplyee(string strName, int nYears)
: m_strName(strName) , m_nYears(nYears)
{

};

public:
virtual int GetSalary() = 0;

string GetName()
{
return m_strName;
}

protected:
int m_nYears;
string m_strName;
};

//经理类
class Manager : public Emplyee
{
public:
Manager(string strName, int nYears)
: Emplyee(strName, nYears) //利用基类的构造函数，完成对属性的初始化工作
{

};
public:
virtual int GetSalary()
{
return 5000*m_nYears+10000;
}
};

//普通员工类
class Worker : public Emplyee
{
public:
Worker(string strName , int nYears)
: Emplyee(strName, nYears)
{

};
public:
virtual int GetSalary()
{
return 200*m_nYears+2000;
}
};

};
