Help with question bank for a trivia game

[kurtangle13]

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.
