CHAPTER 27: LOCAL VARIABLES
- Notes
-
- Read Chapter 27
- On page 197, I say, "What we have not yet seen is a way to
introduce one or more new local, lexically scoped variables that will
be used only within the body of a single function." In the course
notes, however, I have told you about one such
way---
&optional arguments. In this chapter, you will
learn about another way.
- Do Exercises 27.1 - 27.8. After doing Exercise 27.8,
compare your definition of
quicksort with the one in
Appendix A.
- Create a file named
ch27.cl containing a
definition of quicksort according to the specifications
in Exercise 27.9. Make sure this is in the ch27
package. Submit this file.
