NEED HELP WITH HANGMAN

[Destroyer9889]

I have to finish this program by friday and I have no idea how to do the rest. it cannot contain any loops.

#include <iostream>
#include <string>

using namespace std;

const int MAX_TRIES = 6;
const string TITLE_1 = "-------------------------";
const string TITLE_2 = "_                       _";
const string TITLE_3 = "_        HANGMAN        _";
const string TITLE_4 = "_                       _";
const string TITLE_5 = "-------------------------";

const char REPLACE_LETTER = '_';

void main()
{
	string gallows1 = "|-----|---";
	string gallows2 = "|         ";
	string gallows3 = "|         ";
	string gallows4 = "|         ";
	string gallows5 = "|         ";
	string gallows6 = "|______   ";


	string displayWord = "_ _ _ _ _ _";

	string hiddenWord = "BASICS";

	string alphabet = "ABCDEFGHIGKLMNOPQRSTUVWXYZ";

	string hangedMan1, hangedMan2, hangedMan3;


	char userGuess;
	int guessCount = 0;

	// Start screen.
	cout << TITLE_1 << endl << TITLE_2 << endl << TITLE_3 << endl << TITLE_4 << endl << TITLE_5 << endl;
	system("pause");
	system("cls");
	
	// Gallow Display.
	cout << gallows1 << endl;
	cout << gallows2 << hangedMan1 << endl;
	cout << gallows3 << hangedMan2 << endl;
	cout << gallows4 << hangedMan3 << endl;
	cout << gallows5 << endl;
	cout << gallows6 << endl << endl;
	
	// HUD
	cout << alphabet << endl;
	cout << displayWord << endl << endl;
	// User Guess
	cout << "Your Guess: " << endl;
	cin >> userGuess;
	
		if (userGuess == hiddenWord[0])
		{
			displayWord[0] = hiddenWord[0];
		}
		else if (userGuess == hiddenWord[1])
		{
			displayWord[1] = hiddenWord[1];
		}
		else if (userGuess == hiddenWord[2])
		{
			displayWord[2] = hiddenWord[2];
		}
		else if (userGuess == hiddenWord[3])
		{
			displayWord[3] = hiddenWord[3];
		}
		else if (userGuess == hiddenWord[4])
		{
			displayWord[4] = hiddenWord[4];
		}
		else if (userGuess == hiddenWord[5])
		{
			displayWord[5] = hiddenWord[5];
		}
		
	



	system("pause");
