    Default How to "shuffle" an array using random numbers?

    For a project we have to "shuffle" items in an array using random numbers. We are supposed to generate random numbers and use those numbers to exchange array elements. But I am not sure what that means, "exchange array elements". Does that mean you generate 2 random numbers within the length of the array, and then switch the items at those locations in the array? I don't know how I'd do that. Help?

    Default Re: How to "shuffle" an array using random numbers?

    There are several threads on shuffling in this forum. Just search for them. Let's say you have three boxes, all the same size. And two of them are filled with stuff. How do you swap the contents of the two boxes? Once you figure that out you can do the same with array elements.
