(ii) Name the object which gets destroyed in between the program
(iii) Name the operator which is over loaded and write the statement that invokes it.
(iv) Write out the prototype of the overloaded member function
(v) What types of operands are used for the overloaded operator?

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)

case '1': bkd_1-=num;

void Reservation : : disp_stauts (void)
