char username2[6];
int Login;


int User()

cout << "Please Enter a User Id\n";
cout << "User Id must be at least 6 characters long\n";
repeat1:
cin >> username2;
if (username2[6] <= username1)
{
cout << "Please ReEnter Id Not enough characters\n";
goto repeat1;
}

from a quick look, it doesn't look as though you need it, at all..

i made a couple of changes, have a look, is this right??

also i think you need to have a look at the username char limit..

#include <cstdlib>
#include <iostream>
#include <string>
#include <fstream>

using namespace std;

char username1;
char username2[6];
int Login; 

int User()
{
	cout << "Please Enter a User Id\n";
	cout << "User Id must be at least 6 characters long\n";
	repeat1:
	cin >> username2;
	if (username2[6] <= username1)
	{
		cout << "Please ReEnter Id Not enough characters\n";
		goto repeat1;
	}
	else cout << "Your User Id is "<< username2 << endl;
}



int Pass() 
{ 
	repeat2: 

	cout << "Please Enter your password\n";
	cout << "Your password must be at least 7 characters long\n\n>> ";


	string password1;
	string password2;

	cin >> password1;
	cout << "Please ReEnter your password\n";
	cin >> password2;

	if (password1 != password2)
	{
		cout << "You have ReEnter your password incorrectly \n\n";
		goto repeat2;
	}

	else cout << "You Now logged on to treasure Island\n";

}

int Welcome()

{
	cout << "Welcome to Adam's Quiz Game\n";
	cout << "Login Enter 1 " "Create New Account Enter 2 \n" "Press 3 to Quit\n";

	cin >> Login;

	if (Login == 2)
	{
		User();
		Pass();
	}

	if (Login ==1)
	{
		cout << "bye\n";
	}

}


int main()
{
	Welcome ();

	//ofstream dataFile;
	//dataFile.open("data.txt", ios::in|ios::binary|ios::ate);
	//dataFile << username1;
	//dataFile.close();

	system("PAUSE");
	return 0;
}

i didn't test it or anything so tell me how you get on, if it's wrong still ill try have a better look..
