Question :
How to make the creation and deletion of class objects? As I understand the condition, you need to make the creation and deletion of objects at the request of the user.

#include <iostream> #include <string> using std::string; class Mail { private: string zipcode; string city; string street; string room; public: Mail(string zip_ = "00", string city_ = "City", string street_ = "Street", string room_ = "0"); void ChangeZip(string & zip_); void ChangeCity(string & city_); void ChangeStreet(string & street_); void ChangeRoom(string & room_); void showmail() const; ~Mail() { }; }; Mail::Mail(string zip_, string city_, string street_, string room_) { zipcode = zip_; city = city_; street = street_; room = room_; } void Mail::ChangeZip(string & zip_) { zipcode = zip_; } void Mail::ChangeCity(string & city_) { city = city_; } void Mail::ChangeStreet(string & street_) { street = street_; } void Mail::ChangeRoom(string & room_) { room = room_; } void Mail::showmail() const { std::cout << zipcode << std::endl << city << std::endl << street << std::endl << room << std::endl; }
