• Hetergeneous Linked List: [slide view] [print view]

• Macros: [slide view] [print view]

Topics Covered:

• Discussed Project 4

• Finished heterogeneous linked list example.

  Programs shown:

  • Code for HList and the HNode base class: HList.cpp, HList.h.

  • IntNode class derived from HNode: IntNode.cpp, IntNode.h.

  • Test program #1 and output: HLtest1.cpp, HLtest1.txt.

  • DoubleNode class derived from HNode: DoubleNode.cpp, DoubleNode.h.

  • StringNode class derived from HNode: StringNode.cpp, StringNode.h.

  • Test program #2 and output: HLtest2.cpp, HLtest2.txt.

  • Test program #3 and output: HLtest3.cpp HLtest3.txt

  • HStack is a private derivation of HList. HStack.cpp, HStack.h, HStack2.h.

  • Stack tested: HStest1.cpp, HStest1.txt.

  • FIFO queue implemented. Check out source code for HQueue. HQueue.cpp, HQtest1.cpp, HQtest1.txt, HQueue.h.

• Macros: showed how to use macros to write a generic Selection Sort function: swap.cpp, select.h, Main program.

• A good place for documentation on macros: GNU Documentation on Macros.
