Need Help With Hangman Program

[vargoal]

I'm making a program to help construct 4-8 letter words using 12 letters given by user input. I'm still new to c++ and I'm having trouble but i don't know whats wrong.Below is my current code and i appreciate any suggestions.FYI HangManWord.txt is a word list with 58,000 words.

#include <iostream>
#include <string>
#include <vector>
#include <fstream>
using namespace std;
vector<string>PossibleWords;
vector<string>Words;
vector<char>letters;
void initialize();
string MakeWord(){
    for(unsigned int i=0;i<(PossibleWords.size());i++)
    {
        string tmp=PossibleWords.at(i);
        unsigned int test=0;
        for(unsigned int j=0;j<letters.size();j++)
        {
            char tmpc=letters.at(j);
            unsigned int place=tmp.find(tmpc);
            if(place!=string::npos)
            {
                test=test+1;
            }
        }
        if(((tmp.length())==test))
        {
            Words.push_back(tmp);
        }
    }
    string output;
    for(unsigned int i=0;i<Words.size();i++)
    {
        output=output+(Words.at(i))+", ";
    }
    return output;
}
int main()
{
    initialize();
    string input;
    cout<<"Enter your Letters: ";
    getline(cin,input);
    for(int i=0;i<12;i++)
    {
        char tmpstr=input.at(i);
        letters.push_back(tmpstr);
    }
    string answer=MakeWord();
    cout<<answer;
    return 0;
}
void initialize(){ //subroutine that puts word list into vector called "PossibleWords" status: Works
    string line;
    ifstream myfile ("HangManWord.txt");
    if (myfile.is_open())
    {
        while ( myfile.good() )
        {
            getline (myfile,line);
            PossibleWords.push_back(line);
            cout << line << endl;
        }
        myfile.close();
    }
}

i have recently made a hangman program myself that read 200+ words from a .txt file. here's my code

// 230 word hangman.cpp : Defines the entry point for the console application.
// impossible hangman

#include "stdafx.h"
#include <iostream>
#include <string>
#include <windows.h>
#include <stdio.h>
#include <fstream>
#include <vector>
#include <time.h>

using namespace std;

void PrintHeadOfMan(){cout<<" O\n";}
void PrintUpperBodyOfMan(){cout<<"(|)\n";}
void PrintLegsOfMan(){cout<<" ^";}
void PrintDeadMan(){cout<<"v_|o\n";}

int guess=16;
int hints=3;
int guessTemp=16;
string Inputchar;

//our words
vector <string> words;

//our display characters
string displayCharacters;

//timer
void tick(){Sleep(1000);}
//our current word
string currentWord;

//here's where we load the words
void LoadInWords()
{
	ifstream myfile ("hangman.txt");
	if (myfile.is_open())
	{
		string temp = "";

		for(int i =0; myfile.good(); i++)
		{
			getline (myfile,temp);
			words.push_back(temp);
		}
		

		myfile.close();
  }
	else
	{ cout << "ERROR" << endl;}
}

string RandomWord()
{
	return words[rand()%words.size()];
}


//print lives to screen
void PrintLives()
{
	guessTemp=guess/2; 
	while(guessTemp>0)
	{cout<<"M";guessTemp--;}

	cout<<"\n";	

	guessTemp=guess/2;
	while(guessTemp > 0)
	{cout <<"V"; guessTemp--;}
	
	/*if(guessTemp==0)
			
		if (guessTemp>0)
		{system("cls");guessTemp=guess;}
	}*/
}

void PrintLetters()
{
	cout << endl << displayCharacters;
}

void Print()
{
	//clear the screen first
	system("cls");

	PrintLives();
	if(guess<=3){cout<<"      "; PrintHeadOfMan();}

//are we done with the current word?
bool done;

void GetNextMove();
