Computers can't do random numbers. They have to have a special equation
which gives the impression of randomness. The randomness comes from the
modification of a "seed" value which you have to set to a different value
each time you load the program or random will follow the same equation and
return the same values each time you run. The most common way to seed the
random number generator is to seed it with the current system time, as that
will be different each time the program is run.

i = random() % (MaxRandomNumber + 1);
