Homework 8
Maximum Points: 6 plus a possible bonus of 2 points
Due 9:00 am, Tuesday, November 11, 2003

Copy this file to a text file named hw8.txt, edit into it your
answers, and submit the file via the submit program by the deadline
given above.

1. (3) What is printed by the following Java program?

        public class UnaryAsngmntHW8 {
            public static void main (String[] args) {
        	int x=3, y = 0;
        	y = x + --x;
        	System.out.println("x = " + x + " y = " + y);
            } // end of main ()
        }// UnaryAsngmntHW8

2. (3) Rewrite the following C function so that the only control
structures it uses are if, while, and return.  Your function must
return the same value for each possible input as the version below,
and should express the same algorithm.

Bonus: (2 points) Use only one return statement in your version.

int mystery(int x) {
  int r, w, z = 2;
 one: w = 2;
 two: if (w*z == x) goto three;
  w++;
  if (w <= z) goto two;
  if (z+z > x) goto four;
  z++;
  goto one;
 three: r = 0;
  goto five;
 four: r = 1;
 five: return r;
}
