Here is a bit of code from C for Dummies.  The book is terrible in
most parts, but this is a nice llittle thing it did.  It demonstrates
how to go about generating random numbers using the computers time.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int rnd(int range);
int seedrnd(void);

void main(void)
{
	int x;
	seedrnd();
	for (x=o;x<100;x++)
		printf("%i\t",rnd(10));
}

int rnd(int range)
{
	int r;
	r=rand()%range;
	return(r);
}

void seedrnd(void)
{
	srand((unsigned)time(NULL));
}
