Corresponding Reading
---------------------
* K&R Ch. 1-6
* P&H 2.1, 2.3, 2.6, 2.9 page 95,96

Files
-----
Create a directory named ``hw3`` and copy all files from ``~cs61c/hw/03/files``
to that directory.  These files will help you finish question 1 to 4.

Problems
--------

Question 1
~~~~~~~~~~
Complete Exercise 2-3 on page 46 of K&R by filling in the code in ``q1.c``.

Question 2
~~~~~~~~~~
Rewrite the ``bitcount`` function shown on page 50 of K&R such that
it doesn't use any conditional statements such as ``if``, ``switch``,
``?: expression``.  Fill in the code in ``q2.c``.

Question 3
~~~~~~~~~~
Complete Exercise 6-5 on page 145 of K&R.  See the comments in
``q3.c`` for return values of your ``undef`` function.

Question 4
~~~~~~~~~~
Convert the MIPS code in from Exercise 2.29 of P&H into C
statements.  Then fill in the corresponding spaces in ``q4.c`` with
your C statements so that it will produce the correct output.
``$a0``, ``$a1`` and ``$v0`` contains the integers *a* and *b* and
*out* respectively.

Question 5
~~~~~~~~~~
Do Exercise 2.30 from P&H.  Save your answer in a file called ``q5.txt``.

Question 6
~~~~~~~~~~
Complete P&H Exercise 2.32 and save your answer in a file called ``q6.txt``.

Question 7
~~~~~~~~~~
Complete P&H Exercise 2.33 and save your answer in a file called ``q7.s``.

Question 8
~~~~~~~~~~
Complete P&H Exercise 2.36 and save your answer in a file called ``q8.s``.

---------------------------
Save all your files (``q1.c``, ``q2.c``, ``q3.c``, ``q4.c``,
``q5.txt``, ``q6.txt``, ``q7.s``, ``q8.s``) in a directory named
``hw3``.  From the directory ``hw3``, run: ::
