Question on using a while loop?
显示 更早的评论
I have attached my script. I need to Add in code to keep track of the user’s total amount of money (balance), and Display the current balance to the user during each round of play. And At the end of each round, the user should be asked if he/she wants to play again. The games should only continue as long as the user wants to play again and the user still has money left. Im confused on how to keep track of the total balance throughout the game and getting the game to continue on. Would I use a menu statement inside a while loop?

wants_to_continue = true;
while wants_to_continue
...
your existing code
user_choice = input('Do you want to continue? (y/N)', 's');
wants_to_continue = strcmpi(user_choice, 'Y');
end

To add the bet from the total, use:
Bank = Bank + Bet;
Subtraction will be similar, using "-" of course.
To get your program to loop, you could pop up a menu asking if they want to play again. Your while statement would look something like:
while Bank > 0 && play_again
...
end
Where "play_again" is a variable you create to capture the result of the next menu.

Any code that need to run again and again needs to be inside the while loop.
