An unexpected miracle. Programming in the large VS programming in the small.
This is a fragment of an interview with Scientist and former comp1927 student Glen Kelley in which he talks about how they do things in the "real" sciences like biology and physics, and reflects on computing as a science. Recorded to help students think about their approach to task 1 in COMP1927 and shown in class in week 3 session 2 2009.
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 ...more
Computing 2 - Lecture 30: Task 2 and Project Admin Richard talks about the steps in the course project. This is just a course admin lecture but you might be interested in it if you are thinking of giving the project a try yourself.
Finishes off the ideas started in #29. The need for Abstract Data Types (ADTs). How to implement them in C. Their wonderfulness. Also: Undocumented features. Can we trust programmers? Allocating memory on the stack. Allocating memory on the heap (malloc/free). Introduction to the project (card game: Blackadder & Baldrick).
The start of lecture 33 of comp1927. This is just the course admin stuff at the start of the lecture which is probably not interesting to anyone not taking the course.
Featuring discussions of Puritan poetry; The Bay Psalm Book; English metaphysical poetry, including John Donne, George Herbert, Richard Crashaw; Samuel Johnson on Wit; intertextuality; paratext; Michael Wigglesworth; Anne Bradstreet; and Edward Taylor.
Arrays in C. eg calculating the average of a bunch of numbers. man pages - consulting the manual for scanf. debugging by using printf. invalid input to scanf. easy to write an infinite loop!
Examples using arrays in C. eg calculating letter frequencies in a text, substitution ciphers. array initialisers. also: strings, ctype.h
