Extra Problem 1:

Will this program compile and run correctly?  If not, at which line will it
give a warning or error at compile time, or at which line will it crash at
run time?

	main(void)
	{
	  const int * x;
	  int const * y;
	  int * const z;

	  x = 0;
	  y = 0;
	  z = 0;

	  *x = 1;
	  *y = 2;
	  *z = 3;

	  return 0;
	}


Extra Problem 2:

(a) What is the output of the following program:

	#include <stdio.h>
	main(void)
	{
	  float x;
	  float *xp1, *xp2;

	  xp1 = xp2 = &x;
	  ++xp2;
	  printf("xp1 = %d, xp2 = %d, xp2-xp1 = %d\n", xp1, xp2, xp2-xp1);
	  return 0;
	}

(b) How many memory locations are used to store a float?
