Hi, I'm currently working on a trivia game. I have decided to have a question bank (txt file) and it will be read into the program using arrays, this way the program wont be tedious. I also want to randomize the questions for the trivia. I now have a question concerning my randomization. How would you make sure that the questions asked already doesnt get picked again. thanks for your help |

one way to do this would be to have an array of indexes not picked yet. So if you have an array of 5 questions, your other array would be initialized to [0,1,2,3,4] pick and remove a random element from that second array. Lets say it was 2. So you display a question at index 2. You're also left with [0,1,3,4] to choose from next. (or more likely [0,1,4,3,4] with a counter that only first 4 elements are valid. Order is really not essential since you're picking a random number anyway). |

You could have an list (ie. a flexible array) that contains the randomized question numbers. Then, when you ask the question at questionArray[top], pop that element from the array and it will no longer be in the pool of questions you can ask. *edit* Not refreshing pages for 1.5 hours FTL.  |
