>> Well this is CS50. All right, welcome back to the end of week one, this is our last Friday lecture, henceforth they will be Monday and Wednesdays only. A couple of announcements though, zero new handouts but there is code outside if you didn't get it on Wednesday. Office hours will be held one last time this evening for those of you who want to hang out in a group and work on scratch projects or just get help from the teaching fellows and CA's. Cavott [assumed spelling] dining Hall and Quincy dining hall per the, that is entirely false. [Laughter] No more office hours for PSet 0 but they will be held for PSet 1 I'm mis-remembering our own schedule. So office hours will generally be offered on Sunday, Monday, Tuesday, Wednesday, Thursday evenings at different supplies of staff members so do check the course's web site if you would like help with PSet 1 which will be released on the course's web site at 7:00 PM tonight. So this coming Monday we won't have proper sections just yet with your own intimate classrooms with single teaching fellows but rather we'll have a few Super Sections on Monday, Tuesday and Wednesday. Check the courses web site to find out the schedule. These are meant to help you, not only with the first couple of weeks material particularly the C and Linniks but also to help you with PSet 1 which will, again be released this evening but in addition to that, starting this Sunday, led by Marta, one of our teaching fellows, will be, hey Marta, will be the first of several walk throughs so once per week what we do is hold an course wide session that's a code walk through and its really meant to help you get started with the standard addition of the PSet. It will answer such questions as where do I even begin, what is this all about, what might be some strategies for tackling the problems set, those will be Sunday nights, check the web site for the schedule, they'll also be filmed and placed on line, usually by Tuesday so if you can't make it you'll still have that resource and they are meant to eliminate questions of the form and office hours, where do I begin? Finally PSet 1 so, it will in fact go out tonight, this will be your first PSet involving Linniks which may very well may be new topics to some of you. you'll find that the PSet walks you through a lot of the mechanical details that we looked at on Wednesday in great detail so you should not feel yourself in over your head at all and you'll find in the standard edition, which again, is meant for 90 percent of the class, a few challenges. So the first one is going to introduce you to the world of ISBNs. Not a terribly sexy field but these are the numbers that have been stamped on the back of most any book that you've ever purchased. Well it turns out those aren't just random numbers, there's some pattern to them and we can actually detect whether something is or is not a valid ISBN and what you'll find, though very much a bite sized problem, it will non the less get you acclimated, I think fairly well with some basic C syntax and with loops and with manipulating characters and or numbers. So you find that it's a nice introduction to that but then you'll dive into something that's more about thought and more about design.
