#include <iostream>
using namespace std;
class Train
{
    protected :
    int seats_first_class,seats_second_class,seats_ac_2tier;
    public :
   
    void settingSeats()

        cout<<"\nEnter the seats in 2nd class.. \t"; 
		cin>>seats_second_class; cout<<endl;
        cout<<"\nEnter the seats in AC 2 tier.. \t"; 
		cin>>seats_ac_2tier; cout<<endl;
    }
    void DisplayData()
    {
        cout<<"The number of seats in booked by you in 1st class are\t "<<seats_first_class<<endl;
        cout<<"The number of seats in booked by you in 2nd class are \t"<<seats_second_class<<endl;
        cout<<"The number of seats in booked by you in AC 2 tier class are \t"<<seats_ac_2tier<<"\n";
    }

//Deriving class Reservation from the Train class

            booked_ac_2tier=false;
            break;
        } 
    }

//Driver class to test the class 
int main()

    Reservation reserve1,reserve12;
    reserve1.settingSeats(); 
    //Setting data for the reserve12
