a) Indicate the link count for each of these files:

Solution:
handout: 2   (the link in the a2 directory, and '.' in the handout directory)
starter: 3   (the link in the a2 directory, '.' in the starter directory, and '..' in splitexpr)
soln: 2   (the link in the a2 directory, and '.' in the soln directory)
wfold.c: 1

b) Suppose the user is cd'd to the handout directory and types:

	ln a2.pdf example.pdf

Solution: a2.pdf's link count will change from 1 to 2
(because there are two links to it; no changes are involved in links to directories)

c) Suppose the user is cd'd to the soln directory and types:

	mkdir new

Solution: soln's link count will change to 3
(because it is now also linked in as ".." in the new directory)
