// Illustration of how to initialize and use the builtin C random number
// generator rand().

// This version creates a "random" seed from the time of day and uses
// this seed to initialize the random number generator. 
//
// Alternatively you could type in a specific value for the seed, i.e.
//
// int seed;
// seed = 3.14159;
// srand(seed);
