(1) Know that:

comments in C++ start with //

comments in a Makefile start with #

(2) Know that the function that initializes
the data members of an instance of a class
is called the:

 CONSTRUCTOR

(3) Know that the :: that separates the
name of the class from the name of the function
in the function definitions in the blah.cc file
(for class Blah or class Blah_C, if you are using
Conrad's naming conventions)... IS CALLED

the 

BINARY SCOPE RESOLUTION OPERATOR


(4) If you have a file called "Makefile" in your
directory, and you just type "make"

What happens?

The first target in the Makefile is the one that
gets run

(2 extra credit points for Stephan Schill)

A "target" is one of those thingies in the first
column followed by a colon:

e.g.

driver: complex.o driver.o
	${CCC} complex.o driver.o -o $@

In this case, "driver" is a target.


(5) What's up with doing "approxEquals" when comparing
doubles?  Why not just use ==?


Answer: becuase doubles are only approximate representations
of real numbers... there is an infinite number of real numbers
between 0 and 1, but only a finite number of bit patterns
for 32 bits (for a float) or 64 bits (for a double)
