so i have this code in which i need to input some data and then the program need to put the data in alphabetical order
the problem is that i cant convert string name to char s1 and s2.
DATA to input:

#include <iostream>
#include <string>

using namespace std;

struct obiectiv {
    int id;
    string name;
    double latitud; 
    double longitud; 
    double cost_vizitare;
};

int main()
{
    int i, k, temp;
    struct obiectiv ob[9];
    cout << "Introduceti obiectivele(maxim 9): ID NAME LATITUD LONGITUD PRICE" << endl;
    for (i = 0; i < 9; i++) {
        cin >> ob[i].id >> ob[i].name >> ob[i].latitud >> ob[i].longitud >> ob[i].cost_vizitare;
    }
struct obiectiv tempob[9];
      struct obiectiv t[9];
      for (i = 0;i < 9;i++) {
          tempob[i] = ob[i];
      }
      int sorted;
      for (k = 0; k < 9;k++) {
          sorted = 1;
          for (i = 0;i < 9;i++) {
              char* s1 = tempob[i].name;
              char* s2 = tempob[i + 1].name;
              if (strcmp(s1,s2) > 0) {
                  t[i] = ob[i];
                  tempob[i] = tempob[i + 1];
                  tempob[i + 1] = t[i];
                  sorted = 0;
             }
          }
          if (sorted == 1) {
              break;
          }
      }
      cout << "alphabetical order: ";
      for (i = 0;i < 9;i++) {
          cout << tempob[i].name << endl;
      }
}
