Course Project - Start thinking about it
Papers will be distributed at the prior weeks lecture for your talk. So, I must have them before noon on Monday to have time to make copies.
The write-up must be in the format shown on the examples on the web page. These must be emailed to the me by the following Lecture.
The TA and I will not fix code. If it does not work or compile then you don't get credit.
Last semesters students suggested not doing too many different assignments. We will try to build on existing assignments.
Discuss, Redesign, and implement last semesters class design. We will break things into parts and everyone will build different pieces while stubbing out the rest.
Grades on the web. How they work - final % - Say what?
Where to find what on the web page.

Data storage for an instance
access levels and inheritance levels (public, protected, private) P. 79
Type of functions - P64. - access, processing, utility, constructors, destructors. Put comments to seperate categories, nice idea.
Smalltalk

According to Stroustrup Friendship is neither inherited nor
transitive.

class A {
friend class B;}

class B {
friend class C;}

class C{
//C is not a friend of A, despite being a friend of a friend of A
}

class D: public B {
// D is not a friend of A, despite being derived from a friend of A
}
