constructor not displaying values in c++ switch statement -

hi im trying build program ferry keep track of free space im stuck trying output values user gave in inside constructor. problem occurs in case 5 im trying output it. loop doesnt work cuz break while loop didnt work either. creating seperate function didnt work. appreciated.

#include <iostream> #include <string> #include <sstream>  using namespace std;  struct cars {     int carlength, carcount;     string registrationnumber;     int carseats; } caaars[100];  void printcars(cars car);    int n, x;  int main() {     int loop = 0;     string mystr, mystr1, mystr2;     int ferrylength;     cout << "the ferry program\n\n";      cout << "please enter length of ferry in meters: ";     cin >> ferrylength;      while (loop == 0) {         system("cls");         cout << "choose vehicle \n\n";         cout << "1: car.\n";         cout << "2: bus.\n";         cout << "3: lorrie.\n";         cout << "4: digger.\n";         cout << "5: print report.\n";         cout << "6: close program.\n\n";         int choice;         cin >> choice;         switch (choice) {          case 1:{             cout << "\nenter amount of cars needed placed on ferry: ";             cin >> x;             cin.ignore();             while (n != x)             {                  cout << "\nplease enter length of car in metres: ";                 getline(cin, mystr);                 stringstream(mystr) >> caaars[n].carlength; //for integers.                  cout << "\nplease enter registration number: ";                 getline(cin, caaars[n].registrationnumber); //for strings , both                  cout << "\nplease enter amount of seats in car: ";                 getline(cin, mystr2);                 stringstream(mystr2) >> caaars[n].carseats;                    n++;             }         }              break;         case 2:               break;         case 3:              break;          case 4:               break;          case 5:          {             int l;              l = 0;             (l = 0; l < x; l++)                   printcars(caaars[n]);         }              break;          case 6:              loop++;             break;         }// end of while loop.      }     return 0; }  void printcars(cars car) {     int p = 1;      system("cls");     cout << "car ";     cout << p; cout << ":" << endl;     cout << "\nthe registration number is: ";     cout << car.registrationnumber << endl;      cout << "\nthe car length is: ";     cout << car.carlength << endl;     cout << "\namount of car seats: ";     cout << car.carseats << endl;       p++; } 

you iterating using n while should use l instead:

case 5:  {     int l;         l = 0;     (l = 0; l < x; l++)           printcars(caaars[l]); }
