Let's design and implement a class that will serve as the starting point for network-based applications. The main interface of the class looks as follows:
class Networking{public: void start_server();public: std::shared_ptr<Networking> get_instance(); void remove_instance();private: Networking(); ~Networking();private: int socket_; sockaddr_in server_; std::vector<sockaddr_in> clients_;private: static std::shared_ptr<Networking> instance_ = nullptr; static int MAX_QUEUED_CONNECTIONS = 1;};
It's natural for the Networking class to be a singleton because we want a single instance to listen for incoming connections. It's also important to have multiple objects, each of which represents a separate connection ...
