    The code might seem to be working now but be aware that there are a couple of things your teacher might frown upon in the code that Skreaminskull gave you:

    First of all, don't ever include a .cpp file, it's wrong, we only include .h or .hpp files, never .cpp!

    Second of all, the code never calls the setseed() function, so the number will not be random at all.

    Third of all, your setseed() function doesn't utilize the unsigned int parameter that you gave it, it just uses some magic number which is not only a poor way of coding, it also looks unfinished, as if you wrote the code to test the functionality and then never finished it?
    How I need a drink, alcoholic in nature, after the heavy lectures involving quantum mechanics.
