class getter rand variable

#include <iostream>
#include <cstdlib>

using namespace std;

class Passenger {
private:
        int ticket ;
        int half ;
    public:
        Passenger(int ticket=rand() % 2, int half=rand() % 2) {                 //  Construct passenger
                cout << "passenger was constructed with " << ticket << " ticket and " << half << " half ticket" <<endl;
        }
        ~Passenger() {
                cout << "passenger was destructed" <<endl;
        }

        int getTicket()const{
            cout << ticket <<endl;
            return ticket;
        };

        int getHalf()const{
            return half;
        };
};


int main(){
    Passenger m;
    m.getTicket();  
}

getTicket always prints 64 instead of the 0 or 1 that prints when the constructor is called

I couldn't fix it with this and i dont know that many things for rand()
