Code

• Passing matrices to functions: we can pass a matrix as is (then we must provide all but the first dimensions--not general) or as a linear array (general solution, but pointer arithmetic must be done by hand). The most elegant (and indeed most general) solution would be to have matrices of non-contigous columns, but this might imply some extra processing; this solution is outlined here.
• This archive contains our first implementation of linked lists (list.h and list.cc) and code for a simple test program (main.cc). It contains a suitable makefile as well.
• This archive contains an implementation of search trees. The implementation has been requested as an assignment for the Fall 2003 incarnation of this course, and the archive contains the handout for the respective assignment (called handout.pdf) as well as my solution (everything else).
• This archive contains an implementation of search trees as a C++ data type (or class). The implementation has been requested as an assignment for the Fall 2003 incarnation of this course, and the archive contains the handout for the respective assignment (called handout.pdf) as well as the official solution (everything else).
• Here is a more or less complete implementation of lists of integers. The implementation contains some techniques (exceptions) about which we shall talk later in the course. This implementation also overloads the subscript opoerator (operator[]) as discussed in class (i.e., as accessor as well as mutator). Note that the mutator is called every time in non-const lists. The accessor is used only on const objects. There is no way of selecting the accessor according to whether we need an lvalue or not without doing some explicit casting.
• An implementation of template lists (including a random iterator over lists) is here.

Detecting memory leaks

A comprehensive tool for detecting memory leaks (and other nasties) which I recommend is valgrind. It is capable of giving you details about the actual place of those memory leaks, and does some other profiling duty.
