用c++写一个学校的工资管理系统

好的，一个学校的工资管理系统可以包含以下基本功能：

1. 员工信息的录入：包括员工姓名、员工编号、身份证号、岗位、薪资等信息。
2. 员工信息的查询、修改和删除功能。
3. 工资计算功能：根据员工的薪资和出勤情况计算工资。
4. 工资发放功能：将计算出的工资发放给员工，并记录发放时间和金额。
5. 工资统计功能：统计每个月的工资支出情况，包括总工资支出和每个员工的工资支出情况。

下面是一个简单的C++代码示例，实现了上述基本功能：

#include <iostream>
#include <string>
#include <vector>

using namespace std;

class Employee {
public:
    Employee(string name, int id, string idCard, string position, double salary)
        : name(name), id(id), idCard(idCard), position(position), salary(salary) {}

    void printInfo() const {
        cout << "Name: " << name << endl;
        cout << "ID: " << id << endl;
        cout << "ID Card: " << idCard << endl;
        cout << "Position: " << position << endl;
        cout << "Salary: " << salary << endl;
    }

    int getId() const { return id; }
    double getSalary() const { return salary; }

    void setSalary(double salary) { this->salary = salary; }

private:
    string name;
    int id;
    string idCard;
    string position;
    double salary;
};

class SalarySystem {
public:
    void addEmployee(Employee employee) {
        employees.push_back(employee);
    }

    void deleteEmployee(int id) {
        for (auto iter = employees.begin(); iter != employees.end(); iter++) {
            if (iter->getId() == id) {
                employees.erase(iter);
                break;
            }
        }
    }

    void modifyEmployee(int id) {
        for (auto& employee : employees) {
            if (employee.getId() == id) {
                double salary;
                cout << "Input new salary: ";
                cin >> salary;
                employee.setSalary(salary);
            }
        }
    }

    void displayAllEmployees() const {
        for (const auto& employee : employees) {
            employee.printInfo();
            cout << endl;
        }
    }

    void calculateSalary() {
        for (auto& employee : employees) {
            double salary = employee.getSalary();
            int attendance;
            cout << "Input attendance of employee " << employee.getId() << ": ";
            cin >> attendance;
            salary *= attendance / 30.0;
            employee.setSalary(salary);
        }
    }

    void paySalary() {
        double totalSalary = 0;
        for (auto& employee : employees) {
            totalSalary += employee.getSalary();
        }
        cout << "Total salary: " << totalSalary << endl;
    }

private:
    vector<Employee> employees;

int main() {

    while (true) {
