Beginner - Programming without Prior Knowledge
3 points by cb03 2440 days ago | 4 comments
Having little or no language of solid programming is where I'm at. What would I like to see? Well, think about this, "I'm alien, I don't speak your language, but if there is a path that show examples of end-path (simple number sets -with fractal enumeration for complex examples) -then, I might be able to interact with a language. Say, throw two stones on the ground -means this many. Or, this cycle is like these two stones. Or maybe, mix these two, get something like this. But, yea, that's where I'm at.

"Fractal enumeration". I'm taking this literally. Racket's graphics library can probably help you with that. It has some examples, too... In a fresh interaction with Racket, you can type the following:

  (require graphics/turtles
  (turtles #t)
And then:

  (serp 30)
[Unfortunately, at least for me, it seems you can't put those commands together--it seems that after startup, it displays each "turtle" as an orange triangle, and the "serp" (Sierpinski triangle) procedure creates a bunch of turtles, so you need to wait for the first turtle to get displayed before creating the rest, or else you'll just see a bunch of orange when they all get displayed.]

Further documentation is here:

And you can find the source for the "turtle-examples" in [Racket folder]/collects/graphics/turtle-examples.rkt.

What exactly are you asking? Are you looking for help learning Arc, or is this a discussion on how to help people learn Arc? Do you want sample programs for anything specific?

Practice the examples in the tutorial yourself:
