Try this:

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

int main (int c, char *v[])
{
  unsigned long x, y, lz, bz;

  if (c < 3) {
    fprintf (stderr, "Useage: %s <int> <int>\n", v[0]);
    return -1;
  }

  x = strtol (v[1], NULL, 0);
  y = strtol (v[2], NULL, 0);
  bz = x & y;
  lz = x && y;

  printf ("%lu & %lu = %lu (%s)\n%lu && %lu = %lu (%s)\n",
    x, y, bz, bz ? "true" : "false",
    x, y, lz, lz ? "true" : "false");

}
