Lecture 9: A simple recursive function - Richard Buckland UNSW

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.
