struct Person {

Person：id+姓名+手機(jī)號(hào)。還可以添加需要的信息，例如：地址、性別
重載了一個(gè)=操作符
通訊錄建立class AddressList

class AddressList {
private:

?? ?vector<Person> information;//通訊錄：好友的信息組成
public:
?? ?AddressList();
?? ?AddressList(const Person&, const vector<Person>& info = {});
?? ?AddressList(const AddressList&);
?
?? ?void Add(const Person&);//添加一個(gè)好友信息至通訊錄
?? ?void Delete();//通過姓名刪除
?? ??? ? ? ? ?//通過電話號(hào)碼刪除
?? ?void Modify();//輸入id 修改姓名and號(hào)碼
?? ?void Search(int);//1:id搜索
?? ??? ??? ? //2：姓名搜索
?? ??? ??? ? //3：號(hào)碼指定搜索
?? ?void Print()const;
?? ?//查看通訊錄所有信息：僅顯示id和姓名，詳細(xì)信息輸入id查看?? ?
