Is it possible to implement a while loop instead of using goto? Was told to do so by my professor

So I'm really new to programming, but I'm trying to practice all the time, this is one of my "tests", so a lot of my friends told me that using goto is not advised, so what would be some better ways to code this? Thank you in advance <3

cout << "Hello, " << user << " !\n";
START:
cout << "I am familiar with these search engines:\n";
cout << " 1.Google 2.Yandex 3.Bing\n";
cout << " 4.DuckDuckGo 5.StartPage\n";
cout << "Please input what search engine interests you (1-5): ";
cin >> ngin;

//Google part.
if (ngin == 1) {
    //What loop (Google)
GOOGLE:
    cout << " What would you like to do?\n";
    cout << " 1. Information about Google 2. Set Google as default search engine\n";
    cout << " 3.Go back.\n";
    cin >> what1;
    switch (what1) {
    case 1:
        cout << "Info\n";
        goto END;
    case 2:
        cout << "Google has been set as your default search engine\n";
        goto END;
    case 3:
        goto START;
    default:
        cout << "Please input either number 1 or 2.\n";
        goto GOOGLE;
    }
}
else {
    cout << "Incorrect input. Try again.";
        goto START;
    
}
    //End loop, if case number 2 is chosen the program stops.
    END:
    cout << "Would you like to continue?\n";
    cout << "1.Yes 2.No\n";
    cin >> cont;
    switch (cont) {
        default:
            cout << "Incorrect input. Use only stated numbers.\n";
            goto END;
        case 1:
            goto START;
        case 2:
            cout << "See you next time!\n";
            break;
    }

}
