Program Termination

[cyberCLoWn]

If you have a look at thise code, how could I terminate the program as mentioned in the example?

#include <iostream>
using std::cout;
using std::cin;

// Prototypes
void firstClass( int [], int );
void economyClass( int [], int );
void boardingPass( int, int );

int main()
{
   const int numberSeats = 9;
   int airlineSeats[ numberSeats ] = { 0 };
   int choice = 0;
   
   do {
      cout << "\nPress 1 for \"First Class\""
           << "\nPress 2 for \"Economy Class\""
           << "\nPress 3 to Quit"
           << "\n\nEnter your choice: ";
      cin >> choice;
   
      switch( choice )
      {
         case 1:
                  firstClass( airlineSeats, numberSeats );
                  break;
         case 2: 
                  economyClass( airlineSeats, numberSeats );
                  break;
         case 3:
                  return 0;
                  break;
         default:
                  cout << "Woops! Try again.\n";
      }
   } while( choice != 3 );
   
   cin.get();
   return 0;
}

void firstClass( int seat[], int size )
{
   static int placeFirst = 0;
   const int type = 1;
   char otherTicket;
   
   if( placeFirst > size - 5 )
   {
      cout << "\nFirst Class is unfortunately fully booked!\n"
           << "Would you like an \"Economy Class\" ticket? [y/n] ";
      cin >> otherTicket;
      
      if( otherTicket == 'y' )
         economyClass( seat, size );
      else
         cout << "\nNext flight leaves in 3 hours.";
I want the program to terminate here 
   }
   else   
   {
      seat[ placeFirst ] = 1;
      ++placeFirst;
      boardingPass( type, placeFirst );
   }
}

void economyClass( int seat[], int size )
{
   static int placeEcon = 5;
   const int type = 2;
   char otherTicket;
   
   if( placeEcon > size )
   {
      cout << "\nEconomy Class is unfortunately fully booked!\n"
           << "Would you like a \"First Class\" ticket? [y/n] ";
      cin >> otherTicket;
      
      if( otherTicket == 'y' )
         firstClass( seat, size );
      else
         cout << "\nNext flight leaves in 3 hours.";
I want the program to terminate here 
   }
   else   
   {
      seat[ placeEcon ] = 1;
      ++placeEcon;
      boardingPass( type, placeEcon );
   }
}

void boardingPass( int firstSecond, int seating )
{   
   cout << "\n**************************"
        << "\nBOARDING PASS"
        << "\n\n";
        
   if( firstSecond == 1 )
      cout << "First Class\n";
   else
      cout << "Economy Class\n";
      
   cout << "Seat number: " << seating
        << "\n**************************\n";
}

As always, help is appreciated.

You can use the exit(0) function in cstdlib.
Not exactly sure where you wanted it but just put it there.

If you want the program to actually terminate, return your termination flag (3) and put it in choice:

choice = economyClass( airlineSeats, numberSeats );

But if you are going to do that, best to not "hard code" the value. Set up your 3 values as #defines

#define EXIT 3
#define FIRST 1
#define ECONO 2

and use the alias. This way if you wish to change EXIT to 0 you don't have to search thru your code to find all the values.

You can raise exception
