Question

In problems set 1, question 3, the solution has a while loop where the condition is simply "True". How does that loop ever end?

Answer 1

you'd have to post the full code. as far as I can tell
```
while(true){
//do stuff
break; //necessary to break an otherwise infinite loop
}
```

Answer 2

In that type of setup, the while loop won't ever end. Usually something in the code block will break out of the loop, ending it. Don't think it's a silly idiom. It's very useful for waiting for connections in server sockets or waiting for events in GUIs ( Graphical User Interface ).
