This week we covered data representation (character and integer) in computers,
some advanced issues of built-in types and overflow. These topics are not
from the books. Thus, please refer to the ppt file (6.1-number-representation.ppt).
We skipped "floating point representation" part, which is at the end of
this ppt file; you are not responsible for floating point representation.
Midterm 2 coverage is until the end of this topic.
We did not finish everything this week but will complete this topic in
