C++ Login System help.

I'm new to C++.
I have a text file named idpw.txt which is storing id and password
e.g
admin password
account1 abc
john hello

Here's my code so far:

Code:

bool login()
{
 string user[10],password[10], user1, password1;
 ifstream myfile("idpw.txt");
 
 cout << "Please enter your username" << endl;
 cin >> user1;
 cout << "Please enter your password" << endl;
 cin >> password1;
 
 int i=0;
 int j=0;
 while (!myfile.eof())
 {
  myfile >> user[i] >> password[i];
  i++;
 }
 myfile.close();
 
 for (j=0; j<i; j++)
 {
  if (user1 == user[j] && password1 == password[j])
  {
   cout << "Successfully Login" << endl;
   return true;
  }
 }
}

I can login successfully, but here's the problem.
I want to do it in a sense that:
1) When username is correct, but password is wrong, error message will be : "Wrong Password"
2) When username is not in the list, error message will be : "No such user exist"
3) If a user typed in wrong password for 3 times, account will be locked.

Am I doing the login function right? The for loop for int j seems really wrong.
Is there a way to do this?

Thanks alot in advance.
