c++职工工资管理系统

以下是一个简单的C++职工工资管理系统的实现，包括添加员工、查询员工、显示员工信息、删除员工信息、修改员工信息以及退出系统等功能。具体实现如下：

#include <iostream>
#include <string>
#include <vector>
using namespace std;

// 员工类
class Employee {
public:
    Employee(string id, string name, string gender, int age, double salary, double workHours) {
        this->id = id;
        this->name = name;
        this->gender = gender;
        this->age = age;
        this->salary = salary;
        this->workHours = workHours;
    }
    string getId() {
        return id;
    }
    string getName() {
        return name;
    }
    string getGender() {
        return gender;
    }
    int getAge() {
        return age;
    }
    double getSalary() {
        return salary;
    }
    double getWorkHours() {
        return workHours;
    }
    void setSalary(double salary) {
        this->salary = salary;
    }
    void setWorkHours(double workHours) {
        this->workHours = workHours;
    }
private:
    string id; // 工号
    string name; // 姓名
    string gender; // 性别
    int age; // 年龄
    double salary; // 工资
    double workHours; // 工时
};

// 员工管理类
class EmployeeManager {
public:
    // 添加员工
    void addEmployee(Employee employee) {
        employees.push_back(employee);
    }
    // 查询员工
    Employee* findEmployee(string id) {
        for (int i = 0; i < employees.size(); i++) {
            if (employees[i].getId() == id) {
                return &employees[i];
            }
        }
        return NULL;
    }
    // 显示所有员工信息
    void showAllEmployees() {
        for (int i = 0; i < employees.size(); i++) {
            cout << "工号：" << employees[i].getId() << "，姓名：" << employees[i].getName() << "，性别：" << employees[i].getGender() << "，年龄：" << employees[i].getAge() << "，工资：" << employees[i].getSalary() << "，工时：" << employees[i].getWorkHours() << endl;
        }
    }
    // 删除员工
    void deleteEmployee(string id) {
        for (vector<Employee>::iterator it = employees.begin(); it != employees.end(); it++) {
            if (it->getId() == id) {
                employees.erase(it);
                break;
            }
        }
    }
    // 修改员工信息
    void modifyEmployee(string id, double salary, double workHours) {
        for (int i = 0; i < employees.size(); i++) {
            if (employees[i].getId() == id) {
                employees[i].setSalary(salary);
                employees[i].setWorkHours(workHours);
                break;
            }
        }
    }
