- Notes
-
- Read Chapter 4.
- Run
XEmacs and ACL within it.
- Do Exercises 4.1 through 4.15.
- Divide your XEmacs window into two by typing
C-x 2
- In one of the two XEmacs windows, start a file called
ch4.cl by typing C-x C-f ch4.cl
- Note that the mode line of the ch4.cl window is "Common Lisp",
which is the mode for creating Common Lisp source files.
- Cut and paste the following into your ch4.cl buffer:
----------------------- cut here -----------------------
;;; Answers to Chapter 4 Exercises
;;; 4.16
???
;;; 4.17a
???
;;; 4.17b
???
;;; 4.17c
???
----------------------- cut here -----------------------
- Save your ch4.cl file by typing
C-x C-s while your
cursor is inside its window.
- Use the *acl* window to work out the answers to Exercises 4.16
and 4.17.
Each of the four answers is to be a Lisp form (a list in all
four cases) that Lisp evaluates to be the same number that is the
value of the expression shown in the book. For example, the value of
the expression in 4.17b should be 18.8496, and the value of the
expression in 4.17c should be about 32.76.
When you have a correct form for each of the parts, copy it into the ch4.cl
window, replacing the appropriate "???".
- When you are satisfied that you have 4.16 and 4.17 correct,
save ch4.cl by entering
C-x C-s inside its window.
- Submit your ch4.cl file by evaluating the Lisp form
(shell "submit_cse202 ch4.cl")
This is how you are to submit work in this course from now on, unless
told otherwise.
