Hi
I am just starting out with windows programming, i received an exercise to create a windows programme that requests the user to enter a username and password and then validates the password.

Is the only way to do that via a sql file(where the username and password is stored?) I have not started working on sql yet and wonder if i can do storing of the details in the code as well as the validation?

Help will be appreciated, as the responses i get from google all indicate a sql database should be used.

Thanks

Well you do not have to use a database, it makes things easier. You have to store the data somewhere....

string username;
string password;

std::cout << "username: ";
getline(std::cin, username);
if (username == "Raymond") {
std::cout << "password: ";
getline(std::cin, password);
if (password != "1234") {
std::cout << "invalid password. try again." << std::endl;

The database is not the only place where you may store the password: you may use as well a file. However make sure to store NOT the passwords themselves but their hashes. See the following article OriginalGriff's tip for a guideline: Password Storage: How to do it.[^].

No, noooo!

I know that you can do this with the SQL. But you can do evrything in C++!

1. Create a folder called "Login Panel" (I recomend this name)

2. Create 2 files:
username.txt
password.txt
NOTE: The code must be in the same folder!

3. The code:

C++

#include <iostream>
#include <fstream>
using namespace std;

int main () {
  ofstream myfile;
  while(true)
  {
     string password;
     string username;
     cout << "Username: ";cin >> username;
     cout << "Password: ";cin >> password;
 
     myfile.open ("password.txt");
     myfile << password;
     myfile.close();

     myfile.open ("username.txt");
     myfile << username;
     myfile.close();
  }
  return 0;
}</fstream></iostream>

I'd like I was helpful!
