how to add loop in c++

im new to this programming stuff and I was wondering if someone could help me add a loop to my program?

cout << "What do you do?" "\n";
    cout << "\n";
    cout << "(Press Enter...)";
    cin.ignore();
       cout << "\n";
        cout << "Stay in bed?" "\n";
        cout << "Go to the bathroom?" "\n";
        cout << "Go downstairs?" "\n";
    cout << "\n";

    string answer;
    getline(cin, answer);

        if (answer == "stay in bed", "Stay in bed")
            {
                cout << "You lay there, motionless. Silent.";
            }

        else if (answer == "go to the bathroom", "Go to the bathroom")
            {
                cout << "You get up and walk across the hall to the bathroom";
            }
        else if (answer == "go downstairs", "Go downstairs")
            {
                cout << "You get up and walk downstairs to the kitchen.";
            }
        else
            {
                cout << "That is not a valid answer...";
            }
           cin.ignore();

Heres the code. How should I add a loop to where when user enters something falling under the condition of "else", the loop returns to ask "What do you do?". Any help is greatly appreciated. And like I said Im very new to all of this so sorry if this question is so basic that its stupid...
