C++ password program issue. Syntax i think?

Hello peoples, I have made a program that is supposed to check a passcode and it the passcode is correct then it tells you so but if not it gives you another chance to try. It is very simple program because I am very new to C++. the code is below:

Code:

---

#include <iostream>
using namespace std;

int main(void)
{
        bool loop = false;
        int password = 2554;
        int guess;
       
        while(loop == false){
                cout << "Please enter your passcode: ";
                cin >> guess;
               
                if(guess == password){
                        cout << "your passcode was correct thank you";
                        loop = true;
                }
                if(guess != password){
                        cout << "you passcode is incorrect, please try again";
                }
               
        }
        return 0
}

---

This is the error message:

Code:

---

password.cpp:24:1: error: expected ‘;’ before ‘}’ token

---

I have tried many ways but I think its a sneaky syntax somewhere.

I think the line

Code:

---

return 0

---

be

Code:

---

return 0;
