好的,我可以为您提供一个简单的杂志订阅系统的 C++类设计,如下所示:
```cpp
#include <string>
#include <vector>
class Subscriber {
public:
Subscriber(const std::string& name, const std::string& address, const std::string& email)
: name_(name), address_(address), email_(email) {}
std::string getName() const { return name_; }
std::string getAddress() const { return address_; }
std::string getEmail() const { return email_; }
private:
std::string name_;
std::string address_;
std::string email_;
};
class Magazine {
public:
Magazine(const std::string& name, const std::string& publisher, int issueFrequency)
: name_(name), publisher_(publisher), issueFrequency_(issueFrequency) {}
std::string getName() const { return name_; }
std::string getPublisher() const { return publisher_; }
int getIssueFrequency() const { return issueFrequency_; }
private:
std::string name_;
std::string publisher_;
int issueFrequency_;
};
class Subscription {
public:
Subscription(Magazine* magazine, Subscriber* subscriber)
: magazine_(magazine), subscriber_(subscriber) {}
Magazine* getMagazine() const { return magazine_; }
Subscriber* getSubscriber() const { return subscriber_; }
private:
Magazine* magazine_;
Subscriber* subscriber_;
};
class MagazineSubscriptionSystem {
public:
void addSubscriber(Subscriber* subscriber) { subscribers_.push_back(subscriber); }
void removeSubscriber(Subscriber* subscriber) { /* TODO */ }
void addMagazine(Magazine* magazine) { magazines_.push_back(magazine); }
void removeMagazine(Magazine* magazine) { /* TODO */ }
void subscribe(Magazine* magazine, Subscriber* subscriber) {
Subscription* subscription = new Subscription(magazine, subscriber);
subscriptions_.push_back(subscription);
}
void unsubscribe(Magazine* magazine, Subscriber* subscriber) { /* TODO */ }
std::vector<Subscriber*>& getSubscribers() { return subscribers_; }
std::vector<Magazine*>& getMagazines() { return magazines_; }
std::vector<Subscription*>& getSubscriptions() { return subscriptions_; }
private:
std::vector<Subscriber*> subscribers_;
std::vector<Magazine*> magazines_;
std::vector<Subscription*> subscriptions_;
};
```
这个系统包括了三个类:`Subscriber`,`Magazine` 和 `Subscription`,以及一个系统管理类 `MagazineSubscriptionSystem`。
- `Subscriber` 类表示杂志的订阅者,包含订阅者的姓名、地址和邮箱。
- `Magazine` 类表示杂志,包含杂志的名称、出版商和发行频率。
- `Subscription` 类表示订阅关系,包含一个杂志和一个订阅者。
- `MagazineSubscriptionSystem` 类是系统管理类,包含添加/删除订阅者、添加/删除杂志、订阅/取消订阅等功能,并通过三个向量来维护系统中的所有订阅者、杂志和订阅关系。
这只是一个简单的设计,可以根据实际需求进行修改和扩展。
