Reply:I don't know how one would do it in C++, but I know what you would need to do from experience in other languages:





Create a array, with the needed numbers in it. That will assign each number to 1-4, ie 1 is 4, 2 is 8 and so on. Then generate a random number between 1 and 4, and use the generated number to call the entry from the array.
