Does anyone know how to fix "[Error] expected primary-expression before '.' token" problem?

Question

This is the code that I made.

#include <iostream>
#include<bits/stdc++.h>

using namespace std;

struct Account {
  string username;
  string password;
};

struct Schedule{
    char place[100];
    char time[100];
};

bool validatePassword(const string& password) {
  const regex pattern("^(?=.*[A-Za-z])(?=.*\\d)(?=.*[@$!%*?&])[A-Za-z\\d@$!%*?&]{8,}$");
  return regex_match(password, pattern);
}

void createAccount() {
  Account newAccount;
  string password;

  // Get user input for username
  cout << "Enter Username: ";
  getline(cin, newAccount.username);

  do {
    // Get user input for password with validation
    cout << "Enter Password (minimum 8 characters with at least 1 number and 1 special symbol): ";
    getline(cin, password);
  } while (!validatePassword(password));

  newAccount.password = password;

  // Open file for writing account in append mode
  ofstream outfile("accounts.txt", ios::app);

  if (outfile.is_open()) {
    outfile << newAccount.username << endl;
    outfile << newAccount.password << endl;
    outfile.close();
    cout << "Account created successfully!" << endl;
  } else {
    cerr << "Error opening file for account storage!" << endl;
  }
}

void Tickets(){
    int ticket, pw;
    
    reset:
    cout << "Enter your Password: ";
    cin >> pw;
    if (pw == Account.password){
        cout << "How many tickets will you order?: ";
        cin >> ticket;
        
        cout << "Thank you for ordering!"<<endl;
    }
    else {
        cout << "Invalid Password. Try Again!" << endl;
        goto reset;
        system ("pause");
    }
}

void Book(){
    Schedule location[100] ={   
        {"San Mateo", "5:00"},
        {"Sta. Lucia", "5:30"},
        {"Santolan", "5:35"},
        {"Cubao", "4:00"},
        {"Philcoa", "4:30"},
    };
    
    for(int i = 0; i < 6; i++){
        cout << location[i].place << endl;
    }
}
int main(){
    int choice;
    
    do{
        cout << "=== MKD Bus Ticket System ===" << endl;
        cout << "1. Create Account" << endl;
        cout << "2. Order Ticket" << endl;
        cout << "3. Book Schedule" << endl;
        cout << "4. View Schedule" << endl;
        cout << "5. Display Account" << endl;
        cout << "6. EXit" << endl;
        
        cin >> choice;
        cin.ignore();
        
        switch (choice){
        case 1:
            cout << "Account Creation screen" << endl;
            createAccount ();
            break;
        case 2:
            cout << "Order Tickets" << endl;
            Tickets ();
            break;
        case 3:
            cout << "Booking" << endl;
            Book ();
            break;
        case 4:
            cout << "Schedule Viewer" << endl;
            break;
        case 5:
            cout << "Account Information" << endl;
            break;
        case 6:
            cout << "Exit" << endl;
            break;

        }
    }while (choice != 6);
}

Its not complete yet, but I want to point something out that is bugging me. At line 56, the error where primary expression is expected before '.' token keeps popping up. Is there a way to fix this problem?

I tried adding newAccount in the Tickets() function. but it wasn't working. I expected it to work but it didn't fixed the error.

Line 56 is this:

    if (pw == Account.password){

Account is the name of a type, and password is an instance field of that type. Therefore Account.password does not identify an object that you can compare to pw. Presumably, you want to compare to the password member of some existing Account instance, but it's not clear which one. Even your createAccount() function does not provide an Account instance that survives completion of that function.
