Hi,
Basically I'm trying to tie in 3 different classes by using definitions in one class (reference) in another class(library), and then use the function that uses that object in another class(menu). I realize that I could just dump it all in any one of them and be done with it, but my instructor wants it done like this. Can anyone help?

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

using namespace std;

void reference::viewWord()
{
	for(i = 0; i < 5; i++)
	cout << i + 1 << ". " << word[i] << endl;
	cout << " " << 	endl;
}

string reference::getWord()
{
	ifstream inData;

    inData.open("Words.txt"); // Opens quotes txt.

    for(i = 0; i < 5; i++) // A for statement that will be used to house the lines of quotes.txt.
    {
        getline(inData, word[i]);
    }

	inData.close();

	return word[5];
}
string reference::placeWord()
{
	ofstream outData;
	
    outData.open("Words.txt"); // Creates the text document addedQuotes.
	cout << " " << endl;
	cout << "To replace a word with your own word." << endl;
	cin >> newWord;
	cout << " " << endl;
    cout << "Please enter the number of the felling that you would like to change then press ENTER." << endl;
	cout << " " << endl;
    cin >> overideWord;

	word[overideWord - 1] = newWord;

	for(i = 0; i < 5; i++)
	{
		outData << word[i] << endl;
	}

	cout << "To view your word, please check the file called userWord.txt." << endl;
	cout << " " << endl;
    outData.close();
	return word[5];
}

reference::reference()
{

}
#include <iostream>
#include <string>

#include "Library.h"

using namespace std;

string library::chooseReference()
{

	cout << "Do you wish to replace a word?" << endl;
	cout << " " << endl;
	cout << "Please enter y then the ENTER button." << endl;
	cout << "If not please press any key and enter to continue with the game." << endl;
	cout << " " << endl;

	cin >> chooseWord;

	cout << " " << endl;

		switch (chooseWord)
		{
		case 'Y':
		case 'y':
				
			say.getWord();
			cout << "These are all the word." << endl;
			cout << " " << endl;

			
			say.viewWord();
			cout << " " << endl;
			cout << "Please enter your own word." << endl;
	
			// The function below is going to allow the user to change one of the quotes.
			cout << " " << endl;
			say.placeWord();
			cout << " " << endl;

			cout << "This is the new list of quotes." << endl;
			cout << "" << endl;
			say.viewWord();
			cout << " " << endl;
	
			cout << "You now have the option of redoing your word." << endl;

			chooseReference();
			
			cout << " " << endl;	
		
		default:

		}
}

				place.chooseReference();

	}
}

int menu::getNumOfColor()
{
	s = changeName();
	n = s.size();
    return n;
}

int menu::findFirstNum() throw(int)
{
		try
		{
			cout << "Please enter a number between 2 and 6 as your first number." << endl;
			cout << " " << endl;
			cin >> firstNum;
			cout << " " << endl;
	
			if (firstNum > 6)
				throw firstNum;
			else if(firstNum < 2)

		}

So what's the problem? Can you break it down to a specific section or method of one of the classes?

Sorry about the wait. I just got in range of some wifi. The problem sorted itself out. I was trying to use composition in the same two classes and it produced an error as a result. Thanks for taking the time to help though.
