I am having trouble with a problem I am working on. The code works until I get to the next step which is a menu asking if the player wants to play the same game again. I can't seem to get it to loop back to the correct spot.

Maybe I should include the problem so you could see why I did those codes.

You have written three functions for three different games. The names of the games (and the functions that implement them) are Dunko, Bouncer, and Munchies. Each function will accept an integer between one and three indicating the level of difficulty (1 = easy, 3 = hard), and when play is complete will return a text string, either "won" or "lost", to the program that executed the function. Write a program that will use a menu to ask the user if he or she wants to play a game. If not, the program should terminate. If so, the program should generate another menu to allow the user to select one of the three games by name. After selecting a game, the program should display another menu asking the user for the desired level of difficulty (Easy, Moderate, or Hard), and the game should begin by calling the appropriate function. When the user has finished playing the selected game, a message should be displayed indicating whether the user won or lost the game. A menu should then be generated asking if the user wished to repeat the game just played. (THIS IS WHERE I'M STUCK). If so, the difficulty level menu should be displayed again and the game repeated. If the user does not wish to repeat the same game, the program should display a menu asking if the user wants to play another game. If so, the game selection menu should be generated again, followed by level selection, etc. If the user does not wish to play another game, the program should display a message saying "Thanks for playing" and terminate.

You probably want a

while true

external loop though. Yours is using i >= 1, but for the code you have shown you never increment i and unless you are going to use i in some way there is no need to have it there for what is effectively an infinite loop until a break condition is met.

You should just be able to do something like:

while true
   difficulty = menu('Select desired level of difficulty','Easy','Moderate','Hard')
   if games == 1 && difficulty == 1
   ...
   end
   fprintf = ('Thank you for playing')
   replay = menu('Do you wish to repeat the game?','yes','no');
      if replay == 0
         break;
      end
   end
end

editing your existing code in the obvious places to add the new components. This is assuming you mean you want to play the same game and difficulty on answering yes to the question.

Adam,

I added the code above and the menu pops up but no matter if you press yes or no it asks the same "Do you wish to repeat the game?". If you press yes (1) it should go to the difficulty menu. If you press no (2) it should ask the first menu "choice".

Thank you so much for your help with this
