When displayed on the screen, one line copies the other, although they should be different. How to fix?

Question

C++ / C#

The problem is that people copies s when printing the entire array of structures. They are given different values.

#include <iostream>
using namespace std;
enum stran {
    kanada, malasia, turciya,
};
union no {
    int people;
    int s : 10;
};
struct Gosvo
{
    no a;
    string name;
    string sity;
    stran b;
};

int main()
{
    setlocale(LC_ALL, "Russian");
    Gosvo f;
    f.a.people = 9;
    f.name = "Belarus";
    f.sity = "Minsk";
    f.a.s = 2;
    Gosvo k;
    k.a.people = 213;
    k.name = "Brasiliya";
    k.sity = "Brasilia";
    k.a.s = 8;
    Gosvo l;
    struct Gosvo* gs;
    gs = &l;
    gs->a.people = 83;
    gs->name = "Iran";
    gs->sity = "Tegeran";
    gs->a.s = 16;

    int n;
    cout << "Введите количество структур в массиве:";
    cin >> n;
  Gosvo *gosvos=new Gosvo[n];
    gosvos[0] = f;
    gosvos[1] = k;
    gosvos[2] = l;


    cout << "Что делать? Выберите цифру";

    int m;
    cin >> m;
  

   if (m == 1) {

                    gosvos[j + 1].name = b; // значения элементов
                }
            }

    }

Answer 1

Doesn't copy.
You have no - this is a union (union). In a union, all union members occupy the same memory, i.e. if you look at sizeof(no) you will see 4 bytes, i.e. memory is allocated as for one int, and you have 2 ints there. Those. what you wrote in the code is how it works.
Those. operations, for example:

f.a.people = 9;
f.a.s = 2;

overwrite the same area of ​​memory. After that , not 9. f.a.people == 2
