Anoying errror

[lockandstrike]

So here's the deal. I was a making a simple program. Register, Login and Exit but I wanted the password to show up as "*" so I came here and I found a solution but now it gives me an error that I cannot solve.

#include <iostream>
#include <string>
#include <stdlib.h>
#include <conio.h>
using namespace std;

string user, pass, pass1, user1;

int main()
{
	string menu, again, admin;

	do {
		cout << "options \n";
		cout << "register (reg)\n";
		cout << "login (log)\n";
		cout << "exit (exit)\n";
		cin >> menu;

		if ( menu == "reg" ){
			string admin ="";
			char ch;
			cout << "administrator password";
			ch = _getch();
			while(ch != 13){//character 13 is enter
				 admin.push_back(ch);
				 cout << '*';
				 ch = _getch();
			  }
			if ( admin == "jonhy31" ){
				cout << "desired username\n";
				cin >> user;
			}

		}
	}
}

The error is : " error C2059: syntax error : '}' "


P.S.:I use Microsoft Visual C++ 2010 Express Edition

EDIT: The program is not finished because I was trying it on.

you're missing the while portion of the do loop.
the syntax is

do
{
//your code here
}
while (boolean expression);

Thank you. I guess with all the hurry of trying it on I forgot it.
