Lecture Description
We sum the numbers 0..n using gauss, the formula for an arithmetic progression, and finally using a simple recursive program. Apparently summing the numbers 0..n is important in computer science. Along the way we continue our discussion of style and craftsmanship, chainsaws, floats, doubles, longs, side effects. Skating.
Richard explains that this is not a C course. It is a computing course which happens to use C. C is our tool it is not our objective.
Course Description
This is the introductory course for computer science at UNSW.
This course consists of three strands: programming, systems, and general computer-science literacy.
The programming strand is further divided into two parts. For the first half of the course we cover small scale programming, in the second half we look at how to effectively use teams to produce more substantial software.
In the systems strand we will look at how computers work. Concentrating on microprocessors, memory, and machine code.
