Sections 7.1~7.2 on type systems,

Types and type checking are important. You must know what you are working with to handle them properly.

Is C++ using Polymorphism? 291.

Could we do a quick lab using enumerations in class. Just a 15 minute test where we code and compare our work? 297.

Can anything be given the value of void? 301.

Could we go over the example 7.31 in class? Does the result a+b just make it int?

7.7 on pointers,

Pointers are powerful and if understood, can be used for many things.

Example 7.11 on page 348. Why do we have nodes with no information but a pointer to the next node? When is that good. Isn’t that an empty node and should be discarded?

I don’t understand the example on 356 7.86. Why does p not print out &n? is it because n is a local variable to the function foo?

Could you go over figure 7.14 on page 362? I am overwhelmed by it.

7.10 on equality test and assignment

It is very important to know what you want to compare between two objects.

Page 369 example 7.95. Is there a way to check these three tests in C++?

Week 7:

Sections 9.1~9.4 of Programming Language Pragmatics

Spent two hours on the reading. At the beginning I was doing fine with concentrating, but near the end of 9.4 I was really struggling to understand the book. I covered it all and understood about 75 – 80 % of it. I understood it mainly because we went over it in class on Thursday.

Understanding these concepts is the basis of object oriented programming.

It is funny to me that we have been learning object oriented programming this whole time but this is our first reading in Object oriented programming, encapsulation, abstraction, polymorphism, and inheritance.

I understand the concept of extensions or refinements, I’m not sure how to implement them.

What function header do you use to redefine what you want to? Do you use the same name?

Could we go over the example on 452, 453 on linked lists?

Could you explain getters and setters on page 455 at bottom? The example is a little confusing.

Could we have more in class labs where we are given a really easy assignment to try to code, like: write a class and print out the contents, Just really simple hands on examples. Those work best for me.
