使用c++实现机房收费管理系统

机房收费管理系统需要实现以下功能：

1. 学生信息管理：包括添加、删除、修改、查询学生信息等。

2. 机房设备管理：包括添加、删除、修改、查询机房设备信息等。

3. 收费管理：包括学生缴费、退费、查询学生缴费记录等。

4. 统计报表：包括每月学生缴费情况、机房设备使用情况等。

以下是一个简单的机房收费管理系统的代码示例：

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

using namespace std;

// 学生信息类
class Student {
public:
    Student(string name, int id) : name(name), id(id) {}
    string getName() const { return name; }
    int getId() const { return id; }
private:
    string name;
    int id;
};

// 机房设备类
class Equipment {
public:
    Equipment(string name, int price) : name(name), price(price), status(false) {}
    string getName() const { return name; }
    int getPrice() const { return price; }
    bool getStatus() const { return status; }
    void setStatus(bool s) { status = s; }
private:
    string name;
    int price;
    bool status;
};

// 收费记录类
class Payment {
public:
    Payment(Student* s, Equipment* e, int amount) : student(s), equipment(e), amount(amount) {}
    Student* getStudent() const { return student; }
    Equipment* getEquipment() const { return equipment; }
    int getAmount() const { return amount; }
private:
    Student* student;
    Equipment* equipment;
    int amount;
};

// 学生信息管理类
class StudentManager {
public:
    void addStudent(Student* s) { students.push_back(s); }
    void removeStudent(Student* s) {
        for (auto it = students.begin(); it != students.end(); it++) {
            if (*it == s) {
                students.erase(it);
                break;
            }
        }
    }
    void modifyStudent(Student* s, string name) { s->name = name; }
    Student* findStudentById(int id) {
        for (auto it = students.begin(); it != students.end(); it++) {
            if ((*it)->getId() == id) {
                return *it;
            }
        }
        return nullptr;
    }
    void printAllStudents() {
        for (auto it = students.begin(); it != students.end(); it++) {
            cout << "ID: " << (*it)->getId() << ", Name: " << (*it)->getName() << endl;
        }
    }
private:
    vector<Student*> students;
};

// 机房设备管理类
class EquipmentManager {
public:
    void addEquipment(Equipment* e) { equipments.push_back(e); }
    void removeEquipment(Equipment* e) {
        for (auto it = equipments.begin(); it != equipments.end(); it++) {
            if (*it == e) {
                equipments.erase(it);
                break;
            }
        }
    }
    void modifyEquipment(Equipment* e, string name, int price) { e->name = name; e->price = price; }
    Equipment* findEquipmentByName(string name) {
        for (auto it = equipments.begin(); it != equipments.end(); it++) {
            if ((*it)->getName() == name) {
                return *it;
            }
        }
        return nullptr;
    }
    void printAllEquipments() {
        for (auto it = equipments.begin(); it != equipments.end(); it++) {
            cout << "Name: " << (*it)->getName() << ", Price: " << (*it)->getPrice() << ", Status: " << ((*it)->getStatus() ? "In use" : "Available") << endl;
        }
    }
private:
    vector<Equipment*> equipments;
};

// 收费管理类
class PaymentManager {
public:
    void addPayment(Payment* p) { payments.push_back(p); p->getEquipment()->setStatus(true); }
    void removePayment(Payment* p) {
        for (auto it = payments.begin(); it != payments.end(); it++) {
            if (*it == p) {
                payments.erase(it);
                p->getEquipment()->setStatus(false);
                break;
            }
        }
    }
    void printAllPayments() {
        for (auto it = payments.begin(); it != payments.end(); it++) {
            cout << "Student: " << (*it)->getStudent()->getName() << ", Equipment: " << (*it)->getEquipment()->getName() << ", Amount: " << (*it)->getAmount() << endl;
        }
    }
    int getTotalAmount() {
        int total = 0;
        for (auto it = payments.begin(); it != payments.end(); it++) {
            total += (*it)->getAmount();
        }
        return total;
    }
private:
    vector<Payment*> payments;
};

// 统计报表类
class ReportManager {
public:
    void printMonthlyReport() {
        // TODO: 实现每月学生缴费情况统计报表
    }
    void printEquipmentUsageReport() {
        // TODO: 实现机房设备使用情况统计报表
    }
};

// 主函数
int main() {
    StudentManager sm;
    EquipmentManager em;
    PaymentManager pm;
    ReportManager rm;

    // 添加学生
    sm.addStudent(new Student("Tom", 1));
    sm.addStudent(new Student("Jerry", 2));

    // 添加机房设备
    em.addEquipment(new Equipment("Computer", 1000));
    em.addEquipment(new Equipment("Projector", 2000));

    // 学生缴费
    Student* s = sm.findStudentById(1);
    Equipment* e = em.findEquipmentByName("Computer");
    pm.addPayment(new Payment(s, e, 500));

    // 查询学生缴费记录
    pm.printAllPayments();

    // 查询机房设备使用情况
    em.printAllEquipments();

    // 统计报表
    rm.printMonthlyReport();
    rm.printEquipmentUsageReport();

    return 0;
}

以上代码只是一个简单的示例，实际应用中还需要根据具体需求进行修改和完善。
