That doesn't make sense. Cast to `void*` if you want to see the class reference as a pointer. * The text says "for() loop", but you're actually using `foreach` in the code. * If `newButton` "lasts the lifetime of the for() loop", then better declare it in the loop, not as a field of the class. * `return(index);` - Lose the parentheses. `return` is not a function. * You're converting `lastButtonID` from int to string and back to int. That's some pointless back-and-forth.
