I have to convert a previous assignment to add functionality using linked list. The code is commented with placeholders for the rest of the conversion Ie 1a and 1b. I believe once I figure out how to convert and declare the nodes the rest will not be a problem. This is the main program but i believe the issue is in the address book type as I know Ill need to convert the

private:
	extPersonType list[500];

becuase the main reason for doing this is to over come that limit imposed there. Im not sure what all code would be helpful so Ill post the main that the type first.
Here is the code as it stands

//Address Book Main


#include <iostream>
#include <fstream>
#include <string>
#include "addressBookType.h"

using namespace std;

void loadAddressBook(addressBookType& adBook);
void saveData(addressBookType& adBook);
void addEntry(addressBookType& adBook);
void deleteEntry(addressBookType& adBook);
void showMenu();

int main()
{
	addressBookType addressBook;
	string str;
	string str1;
	string str2;
	int choice;
	int loc;
	int month;

	loadAddressBook(addressBook);

	addressBook.sort();

	showMenu();

	cin >> choice;
	cin.ignore(100, '\n');

	while (choice != 0)
	{
		switch (choice)
		{
		case 1: 
			cout << "Enter the last name of the person: ";
			getline(cin , str);
			cout << endl;

			loc = addressBook.search(str);

			if (loc != -1)
				cout << str << " is in the address book" << endl;
			else
				cout << str << " is not in the address book" << endl;
			break;
		case 2: 
			cout << "Enter the last name of the person: ";
			getline(cin , str);
			cout << endl;

			loc = addressBook.search(str);

			if (loc != -1)
				addressBook.printAt(loc);
			else
				cout << str << " is not in the address book" << endl;
			break;
		case 3: 
			cout << "Enter the month number: ";
			cin >> month;
			cin.ignore(100, '\n');
			cout << endl;

			addressBook.printNameInTheMonth(month);
			break;
		case 4: 
			cout << "Enter starting last name: ";
			getline(cin , str1);
			cout << endl;
			cout << "Enter ending last name: ";
			getline(cin , str2);
			cout << endl;

			addressBook.printNamesBetweenLastNames(str1, str2);
			break;
		case 5: 
			cout << "Enter person type Family, Friend, Business: ";
			getline(cin , str);
			cout << endl;

			addressBook.printNamesWithStatus(str);
			break;
		case 6:

			break;
		case 7:

and the type
