Learning, need help with endless loop and quit

[SpiffinSpiff]

Write your question here.
I was wondering how I could put my program into an endless while loop and have it quit when the user enters "quit".
Thanks!

#include <iostream>
#include <string>

int main()
{
    std::string command;
    while(std::cin >> command && command != "quit")
    {
    }
}
