Hi, I'm supposed to create a program where I want to purchase tickets to a theater based on rows and columns of the seats. The program uses two-dimensional arrays and constructors, and is supposed to display somethine like this:
"ASU Gammage Theater
1. View available seats
2. Request tickets
3. Display theater sales report.
4. Exit the Program
"
If I input "1", it'll give me a diagram of the seats available (available is #, unavailable is *).
If I input "2", then it'll give me the following options:
"Number of seats desired (1-30):
Desired row (1-15):
Desired starting seat number in the row (1-30):"
It'll then calculate the total ticket prices based on what row you chose, determine whether those seats are available or not, and then asks you what payment you want to make. It calculates the change that's left after you make the payment.
If I input "3", it'll give me how many seats are available and how many are sold, as well as total revenue.
Here is the code for the main program:
// BEGINNING OF MAIN PROGRAM
#include<iostream>
#include<iomanip>
#include"TicketManager.h"
using namespace std;
int main()
{
TicketManager ticketsGammage;
// Displays Menu
int choice;
do
{
cout << "ASU Gammage Theater " << endl;
cout << endl;
cout << "1. View Available Seats " << endl;
cout << "2. Request Tickets " << endl;
cout << "3. Display Theater Sales Report " << endl;
cout << "4. Exit the Program " << endl;
cin >> choice;
// Displays what seats are available (in rows and columns)
if (choice == 1)
{
ticketsGammage.displaySeats();
}
// Requests the number of seats desired, the desired row, and the desired seat number,
// and returns it to the constructors.
else if (choice == 2)
{
int tickets, row, startSeat;
cout << "Number of seats desired (1-30): ";
cin >> tickets;
cout << endl;
cout << "Desired row (1-15): ";
cin >> row;
cout << endl;
cout << "Desired starting seat number in the row (1-30): ";
cin >> startSeat;
ticketsGammage.requestTickets(tickets, row, startSeat);
}
// Displays how many seats are available.
else if (choice == 3)
{
ticketsGammage.displaySalesReport();
}
// If user wishes to exit program
else if (choice == 4)
{
}
// If the user does not input a valid
else if (choice != 4)
{
return 0;
}
} while (choice != 4);
return 0;

5.00Now, all of the code seems written correctly, but I when I input '2' to request tickets, and then input the number of seats desired, the row desired and the desired seating number, my program keeps going back to the menu. After fiddling with this for around 6 hours, I'm still at an impasse... my instincts are that the problem lies within the Assignmen8.cpp file, where somehow some number keeps screwing with the program, or it's not returning the correct boolean value for the requestTickets constructor.
Any suggestions? Thanks :)
