CASINO GAME CONFUSION do while

gunuwunu (3)
HEY EVEYONE!I need some help with this code!
It is a craps game and a casino menu

the rules for the game go
on the first roll if you roll 7 or 11 user wins bet and must ask the user to play again or go back to the menu
if a 2 3 or 12 is rolled on the first roll, user loses bet and must ask the user to play again or go back to the menu
if a 4 5 6 8 9 10 are rolled then you must ask the user to roll again

on the second roll if the user rolls the same number user wins bet
on the second roll if user rolls 7 user loses bet

I dont understand how to break the do while loop here to roll again for the second roll and how to get the code to roll again if the user wins or loses on the first round
