A railway reservation counter needs to computerise its reservation process. Using the following information write a C ++ program to do so:
class Train {
int number; //Train number
int seats _1; //Total seats in 1st class
int seats _2 ; //Total seats in 2nd class
int seats _3; //Total seats in 3rd class
public;
Train (int i, int j, int k, int l)
{
number = i; seats_1 =j ;
seats-2 =' k;,seats-3 = 1,.
}
int getnum(void)
{ return number; }
int getseats_1(void)
{ return seats_1 ; }
int getseats_2(void)
{ return seats _2 ;}
int getseats - 3 (void)
{return seats - 3:}
};
class Reservation : public Train
{ int bkd_1 ; //Seats reserved in 1st class
int bkd_2 ; ///Seats reserved in 2nd class
int bkd_3 ; ///Seats reserved in 3rd class
public:
int i, j, k, 1;
Reservation (int i, int j, int k, int 1) : Train (i ,j, k,l)
{bkd_1 = bkd_2 = bkd_3 = 0 ; }
void book(char type, int num);
void cancel (char type, int num) ;
void disp_status (void);
};
void Reservation: : book (char type, int num)
{ switch(type)
}
case '1': bkd_1+=num; //addnum to bkd_1
break;
case '2': bkd_2+=num; //addnum to bkd_2
break ;
case '3': bkd_3+=num; Iladdnum to bkd_3
break;
default: cout <<"Wrong class\n";
}
}
void Reservation: : cancel (char type. int num)
{ switch(type)
}
case '1': bkd_1-=num;
break;
case '2': bkd_2-=num;
break ;
case '3' : bkd_3-=num;
break ;
default: cout <<"Wrong class\n" ;
}
}
void Reservation : : disp_stauts (void)
{
cout <<"\t\t Train Numbe r: "< cout <<"Class\t Total seats\t Reserved \t
Unreserved\n" ;
int val;
val = getseats_1 () ;
cout<< "I\t "< xval << "\t "<< bkd_1<< "

val = getseats_2 () ;
cout << "2\t "<< val << "\t "< xbkd 2 << "​​​​​​​​​​​​​​
\t "<< val-bkd_2 << "\n";​​​​​​​
val = getseats_3 ( ) ;​​​​​​​
cout << "3\t "<< val << "\t "<< bkd 3 << "​​​​​​​
