思路分析 为了实现银行排队系统，我们需要设计一个能够处理多个窗口、VIP客户和普通客户的系统。以下是详细的步骤和算法说明： 1. 数据结构设计： - Customer: 表示，包括客户ID、是否为VIP等。 - Window: 表示银行窗口，包括当前正在服务的顾客、等待队列等。 - Bank: 管理所有窗口和客户的整体逻辑。 2. 核心算法： - 客户到达：生成客户ID，如果是VIP客户直接分配到VIP窗口，否则加入普通客户的等待队列。 - 服务窗口：每个窗口轮流从等待队列中取出客户进行服务，并记录服务时间。 - 客户离开：客户完成服务后离开，并可以对服务进行评价。 3. 面向对象设计： - 使用类来封装不同的实体（如Customer, Window, Bank）。 - 使用队列来管理等待的客户。 - 使用优先队列或其他机制来优化VIP客户的服务。 4. 流程图与伪代码： - 描述客户到达、服务窗口、客户离开的流程。 - 提供伪代码以帮助理解算法逻辑。 数据结构与类设计 ```cpp #include <iostream> #include <queue> #include <vector> #include <string> #include <unordered_map> class Customer { public: int id; bool isVIP; std::string serviceFeedback; Customer(int id, bool isVIP) : id(id), isVIP(isVIP), serviceFeedback("") {} }; class Window { public: int windowId; std::queue<Customer*> customerQueue; Customer* currentCustomer; Window(int id) : windowId(id), currentCustomer(nullptr) {} void serveNextCustomer() { if (!customerQueue.empty()) { currentCustomer = customerQueue.front(); customerQueue.pop(); std::cout << "Serving customer " << currentCustomer->id << " at window " << windowId << std::endl; } else { currentCustomer = nullptr; } } void finishService() { if (currentCustomer != nullptr) { std::cout << "Customer " << currentCustomer->id << " finished service at window " << windowId << std::endl; currentCustomer = nullptr; } } }; class Bank { private: std::vector<Window*> windows; std::queue<Customer*> vipQueue; std::queue<Customer*> normalQueue; int nextCustomerId; int vipWindowId; public: Bank(int numWindows, int vipWindowId) : nextCustomerId(1), vipWindowId(vipWindowId) { for (int i = 0; i < numWindows; ++i) { windows.push_back(new Window(i + 1)); } } ~Bank() { for (auto window : windows) { delete window; } } void customerArrives(bool isVIP) { Customer* newCustomer = new Customer(nextCustomerId++, isVIP); if (isVIP && vipWindowId > 0 && vipWindowId <= windows.size()) { windows[vipWindowId - 1]->customerQueue.push(newCustomer); } else { normalQueue.push(newCustomer); } std::cout << "Customer " << newCustomer->id << " arrives" << (isVIP ?
