So, I think we all got something out of tonight. To recap, we covered: * How to help yourself: ri, google, mailing lists * Values, variables, and constants * Arrays * Introspection * Blocks * Why Matt should test his examples before bringing them to class
There's a couple of exercises to be done by about Monday next week, with results sent back to the list for comment and improvement: - Generate a set of 20 random numbers between 1 and 100, and then print only the odd ones -- with the special caveat that your solution *must* use Array#<< and Array#select. Don't know what they do? See the first point above. - Read all lines from standard input, then print them out in a random order. (Hint: Array#sort_by) (Extra hint: There's more to the IO class than each_line -- there are also methods to read lines) Remember, you're not being marked, so there's no point in "hiding" your solutions -- post your ideas early, then you can get feedback from everyone, and improve your code. Also, please e-mail the code you wrote tonight to solve David's rounding problem to the list, and watch the list so you can comment on other people's submissions. I'd like to see at least one suggestion on someone else's code from everyone in the group. - Matt _______________________________________________ coders mailing list [email protected] http://lists.slug.org.au/listinfo/coders
