Hello... I'm practicing c++ and I'm trying to create a program with register and login in it.. the problem is I'm trying to compare the register username/password to the login username/password but even though the comparisons are right it's not working..

#include <Windows.h>
#include <iostream>
#include <iomanip>
#include <string>
#include <fstream>
#include <cmath>

using namespace std;

struct First{

	string user;
	struct{
		char username[10];
		char password[10];
	}signup;

	struct{
		char username2[10];
		char password2[10];
	}login;

	struct{
		char firstname[50];
		char lastname[50];
	}name;

};

int option=0;
int inlog;

int main () 
{
	First A;
	cout << "LOADING PROGRAM...";
	Sleep (2000);
	cout << ".....";

Please help me..

You can not use != or == operator to compare two character arrays, you have to call strcmp() to do that if( strcmp(A.signup.username,A.login.username2) != 0)

Hi Ancient Dragon! I tried the string compare code and it's still not working. :(

If you don't mind me asking, why are you using C-style strings for the username, password, etc., when you've already used a string for the user variable? Wouldn't using a C++ style string be much easier?

Also, I would recommend breaking your program up into separate functions, especially the login operation, which you actually have in two different places that I can see.

Also, your program is not saving the Registered name/password anywhere, so when you start the program and just select Login where is the registered name/password supposed to come from?

And what's with all those Sleep()s? The program isn't actually doing anything when it displays "Loading ..." so why waste everyone's time with that nonsense.
