if (auth()->check() && auth()->user()->id == 3)" this is checking user is authenticated yes or no if logged in then checking user Id if user id == 3 then code execute and id number 3 is identify as a guest user account with aleart message. - In my database phpmyadmin I have a user name with demo and demo's account id is (3) you can find id just visit phpmyadmin -> users -> table, For educational purpose i choosed id "3" you can choose what you want.
{ session()->flash('demo_error', 'You are using a guest account.'); return redirect()->back(); }If user passed auth and logged in then using session flash and help of demo_error key now if user trying to edit admin profile then showing in view an alert message like this " 'You are using a guest account.'

Advantages and Disadvantages
| Advantages | Disadvantages |
| Auth checking and Controlling: If user not authenticated it flashes an error message and redirect to back or homepage. | Update code after every changes: Using this logic if user id is changed then change and update this logic also. |
| findOrfail: using this with parametter $id it specified ID is not exist, and user can't logged in without valid user account. | Lack of Flexibility:This code assumes that only one user (with ID 3) has access to the editing functionality. |
| Easy understandable: this code is easy understandable and clean code. | Hidden Error: If user is not authenticated and user trying to edit then a hidden error execute without any error flashes message, but If you want show a error message your can add. |
| Flash an alert warning message: If user not fulfil it flashes an alert warning message. | Redirect to Back: User is not authorized then might be more appropriate to redirect them to a specific error page or to the homepage. |

Conclusion
In conclusion, the provided code segment illustrates an edit function within a Laravel application. It begins by checking if the user is authenticated and if their ID matches a predefined value (in this case, 3), indicating a guest account. If this condition is met, a flash message is set to notify the user, and they are redirected back.
However, if the user is not a guest, the function proceeds to fetch the user details based on the provided ID and renders a view for editing the user information. This approach ensures that only authenticated users with appropriate permissions can access the edit functionality, maintaining security and control over user interactions.
