That's correct :)

rand returns a value less than the expression so will return an index in the range 0..100. Which is just what we needed -- woot!

    I found your solution confusing since your array had 101 elements and so wouldn't work with the op's data. I realize now this was just a test array of junk values. Your solution works fine for your array of 101 elements since both indexes will be in the range 0..100. Putting the array inside the rand() function is a general solution in case the array size changes.
