Help with Airline Seating Assignment (Array)

[lukemuller]

Hey guys,
I've been having a bit of trouble with my c++ program i'm trying to create for an assignment. I'm still learning, but array's seem to give me the most trouble. I've been reading and searching google alot to try and find examples to help my situation, but i'm not quite sure what i've done so far is correct especially with the array side of things. The program compiles correctly but when i go to test adding a passanger name it gives and unhandled exception error. The requirements for the assignment are:

"You are hired to develop a program to be used by airport staff to assign seats for a commercial airplane.
The airplane has 12 rows. Rows 1 and 2 are first class, rows 3 through 5 are business class, and rows 6 through 12 are economy class."
- You must define and implement a class Passenger to model passenger objects and you must use the class in your program.
- The data structure that is used to store Passenger objects must be array.
- You may use any C++ standard libraries, if you wish.

And my code so far is (sorry i haven't commented it yet aswell) :

#include <iostream>
#include <string>
#include <cstdlib>
#include <sstream>

using namespace std;

class Passenger
{
	string **FirstArray;
	static const int firstClassRow = 2;
	static const int firstClassColumn = 2;

	string **BusArray;
	static const int busClassRow = 3;
	static const int busClassColumn = 4;

	string **EconArray;
	static const int econClassRow = 7;
	static const int econClassColumn = 6;

	static const char Available = '*';
	static const char Occupied  = '+';

public:
	Passenger()
	{
	FirstArray = new string*[firstClassRow];
	for (int i = 0; i < firstClassRow; i++)
		FirstArray[i] = new string[firstClassColumn];

	BusArray = new string*[busClassRow];
	for (int i = 0; i < busClassRow; i++)
		BusArray[i] = new string[busClassColumn];

	EconArray = new string*[econClassRow];
	for (int i = 0; i < econClassRow; i++)
		EconArray[i] = new string[econClassColumn];

	memset(FirstArray, Available, sizeof FirstArray);
	memset(BusArray, Available, sizeof BusArray);
	memset(EconArray, Available, sizeof EconArray);

	void addPassenger(int rowNumber, int columnNumber);
	string getSeat(int rowNumber, int columnNumber);
	};

	~Passenger() {
		for (int i = 0; i < firstClassRow; i++)
			delete [] FirstArray[i];
		delete [] FirstArray;

		for (int i = 0; i < busClassRow; i++)
			delete [] BusArray[i];
		delete [] BusArray;

		for (int i = 0; i < econClassRow; i++)
			delete [] EconArray[i];
		delete [] EconArray;
	}

	void Passenger::addPassenger(int rowNumber, int columnNumber) {
		if (rowNumber <= 2) {
			FirstArray[rowNumber][columnNumber]= "test";
		} else if (rowNumber > 2 && rowNumber <= 5) {
			BusArray[rowNumber][columnNumber]= "test";
		} else {
			EconArray[rowNumber][columnNumber]= "test";
		}
	}
	string Passenger::getSeat(int rowNumber, int columnNumber) {
		string seat;
		if (rowNumber <= 2) {
			seat = FirstArray[rowNumber][columnNumber];
		} else if (rowNumber > 2 && rowNumber <= 5) {
			seat = BusArray[rowNumber][columnNumber];
		} else {
			seat = EconArray[rowNumber][columnNumber];
		}
		return seat;
	}

Any help with this would be greatly appreciated.
Thanks so much guys!
