Hullo,
	To test out my radix_bit_sort function, I've been trying to generate a
list of random numbers to sort, and then sort them. The list is rather
long, 4000, and I'd like it to be ints, but I can' seem to get it! The
program compiles and runs without error, but it gives me #s far larger
than integers when I print out some results. I'm using DJGPP v2.
Here's some of the code...


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

#define NUM 2000

int main()
{

   int ctr;
   int *origp;
   int *onesp, *zerop;
   int ticks;       /* for use with the clock in randomizing shtuff */

   if ( !(origp = (int *)malloc(NUM * 2)) ||
	!(onesp = (int *)malloc(NUM * 2)) ||
	!(zerop = (int *)malloc(NUM * 2)) )
      {
	 printf("Not enough memory to run this program!!!");
      }

   clock();             /* Initialize the clock */
   (int *)ticks = clock();
   srand(ticks);

   for (ctr = 0; ctr < NUM; ctr++) {
      origp[ctr] = rand();
   }

   radix_bit_sort(origp, onesp, zerop, NUM);


   for (ctr = 0; ctr < 20; ctr++)
      printf("%d\n", origp[ctr]);

   free(origp);
   free(onesp);
   free(zerop);

   return 0;
}

I really need some serious help. Thanks.

	nicholas
