Up]

Assigned Reading:  14.1-14.2

Slides As Shown:

• Announcements, etc: [slide view] [print view]

• Inheritance: [slide view] [print view]

• More on Inheritance: [slide view] [slide view]

Topics Covered:

• Project 3.

• Class derivation and inheritance: we discussed how C++ handles compatibility between derived class objects and base class objects.

Programs Shown:

• Box class: Box.h, Box.cpp, boxtest.cpp and boxtest.txt.

• Cube class: Cube.h, Cube.cpp, cubetest.cpp, and cubetest.txt.

• Color cube class: ColorCube.h, ColorCube.cpp,

• Simple use of ColorCube, showing order of construction, destruction, and use of base class methods.
  cctest.cpp, cctest.txt.

• Passing a derived object to a function with base class reference parameters.
  cctest2.cpp, cctest2.txt.

• Passing a derived object to a function with base class value parameters.
  cctest3.cpp, cctest3.txt.

• Same as cctest3.cpp, but bar3() is compiled separately.
  ccsep4.cpp, cctest4.cpp, cctest4.txt.

• Checking out how assignment works, or doesn't.
  cctest5.cpp, cctest5.txt.

• Checking out pointers and dereferencing.
  cctest6.cpp, cctest6.txt.

• C++ lets you do BAAAAD things with arrays of objects.
  cctest7.cpp, cctest7.txt.

• Checking out function overloading and inheritance.
