For the craps game in the tutorial, the client may want to enter a cash amount to bet for each game. If they bet $($e$.$g$.,$ $$5)$ and win, they receive two times their bet $($$$10)$; if they lose, the money they bet $($e$.$g$.,$ $$5)$ goes to the casino.

If you want to allow a player to bet in this way, what core code additions would need to be implemented to track the totalWinnings and the betting results?
