The essence of the problem is this: I need to push a class object onto the stack and then take it out from there, but after I take it out and pass it back from the stack to the object, the class fields are not filled with the values ​​of the object that was passed to the stack. How is this possible to implement?

Here is the code

#include "Pharmacy.h"//мой класс #include "Hospital.h"//мой класс #include <stack> using namespace std; int main() { stack<Pharmacy> stkPharmObj; //стак объектов класса string str; Pharmacy objPharmacy, objPharmacy1, objPharmacy2, objPharmacy3; //Внизу куча текста, для запроса и передачи значений. Знаю, делал через цикл, тоже не работало, но так я хоть уверен, что все ввел. Сорян за количество строк cout << "Input Town" << endl; cin >> str; cin.ignore(); objPharmacy.setTown(str); cout << "Input name" << endl; getline(cin, str); objPharmacy.setName(str); cout << "Input Street" << endl; getline(cin, str); objPharmacy.setStreet(str); cout << "Input NumberBuilding" << endl; getline(cin, str); objPharmacy.setNumberBuilding(str); stkPharmObj.push(objPharmacy);//Вот первый объект в стек cout << "Input Town" << endl; cin >> str; cin.ignore(); objPharmacy1.setTown(str); cout << "Input name" << endl; getline(cin, str); objPharmacy1.setName(str); cout << "Input Street" << endl; getline(cin, str); objPharmacy1.setStreet(str); cout << "Input NumberBuilding" << endl; getline(cin, str); objPharmacy1.setNumberBuilding(str); stkPharmObj.push(objPharmacy1);//Вот второй cout << "Input Town" << endl; cin >> str; cin.ignore(); objPharmacy2.setTown(str); cout << "Input name" << endl; getline(cin, str); objPharmacy2.setName(str); cout << "Input Street" << endl; getline(cin, str); objPharmacy2.setStreet(str); cout << "Input NumberBuilding" << endl; getline(cin, str); objPharmacy2.setNumberBuilding(str); stkPharmObj.push(objPharmacy2);//Вот третий cout << "Input Town" << endl; cin >> str; cin.ignore(); objPharmacy3.setTown(str); cout << "Input name" << endl; getline(cin, str); objPharmacy3.setName(str); cout << "Input Street" << endl; getline(cin, str); objPharmacy3.setStreet(str); cout << "Input NumberBuilding" << endl; getline(cin, str); objPharmacy3.setNumberBuilding(str); stkPharmObj.push(objPharmacy3);//Вот четвертый objPharmacy = stkPharmObj.top();//вот тут я пытаюсь объекту передать значение последнего объекта, должен в этом отображаться объект 3 //функции отображения. objPharmacy.Show();//здэс пустота, поля не пришли из объекта который я пытался достато из стека objPharmacy2.Show();//а здесь все отлична //Хотя стек принял все объекты норм и указал размер 4 system("pause"); } 

Below is the class code

  #pragma once #include "BasikZaklad.h" class Pharmacy : public BasikZaklad { private: string strWorkingKlas, strFormVlas; public: Pharmacy() {}; Pharmacy(const Pharmacy &obj) { setWorkingKlas(strWorkingKlas); setFormVlas(strFormVlas); }; ~Pharmacy() {}; virtual void Show() override { cout << "string strWorkingKlas ==" << getWorkingKlas() << endl; cout << "string strFormVlas ==" << getFormVlas() << endl; BasikZaklad::Show(); } void setWorkingKlas(string strWorkingKlas); void setFormVlas(string strFormVlas); string getWorkingKlas(void) { return strWorkingKlas; } string getFormVlas(void) { return strFormVlas; } }; void Pharmacy::setWorkingKlas(string strWorkingKlas) { try { char* chWorkingKlas{}; int iCountWorkingKlas = 0; if ((chWorkingKlas = (char*)calloc(40, sizeof(char))) == 0) { printf("\nMemory allocation failure\n"); exit(1); } for (int i = 0; ; i++) { chWorkingKlas[i] = strWorkingKlas[i]; if (checkNumbers(strWorkingKlas)) throw chWorkingKlas; if (strWorkingKlas[i] == '\0') break; iCountWorkingKlas++; if (iCountWorkingKlas > 40) throw iCountWorkingKlas; } if (!islower(strWorkingKlas[0])) { this->strWorkingKlas = strWorkingKlas; } else throw strWorkingKlas; } catch (char* chWorkingKlas) { cout << "Error invalid WorkingKlas!!! Wright it without numbers or other chars" << endl; } catch (string strWorkingKlas) { cout << "Error invalid Town!!! Wright it from big letter" << endl; } catch (int iCountWorkingKlas) { cout << "Error invalid Town!!! Too much chars" << endl; } } void Pharmacy::setFormVlas(string strFormVlas) { try { char* chFormVlas{}; int iCountFormVlas = 0; if ((chFormVlas = (char*)calloc(60, sizeof(char))) == 0) { printf("\nMemory allocation failure\n"); exit(1); } for (int i = 0; ; i++) { chFormVlas[i] = strFormVlas[i]; if (checkNumbers(strFormVlas)) throw chFormVlas; if (strFormVlas[i] == '\0') break; iCountFormVlas++; if (iCountFormVlas > 60) throw iCountFormVlas; } if (!islower(strFormVlas[0])) { this->strFormVlas = strFormVlas; } else throw strFormVlas; } catch (char* chFormVlas) { cout << "Error invalid WorkingKlas!!! Wright it without numbers or other chars" << endl; } catch (string strFormVlas) { cout << "Error invalid Town!!! Wright it from big letter" << endl; } catch (int iCountFormVlas) { cout << "Error invalid Town!!! Too much chars" << endl; } }

I watched in Vizhalka for filling, all objects in the stack are empty.
