Here's the course description:

  "Introduction to the intellectual enterprises of computer science and
  the art of programming. This course teaches students how to think
  algorithmically and solve problems efficiently. Topics include
  abstraction, algorithms, data structures, encapsulation, resource
  management, security, software engineering, and web
  development. Languages include C, PHP, and JavaScript plus SQL, CSS,
  and HTML. Problem sets inspired by real-world domains of biology,
  cryptography, finance, forensics, and gaming. Designed for
  concentrators and non-concentrators alike, with or without prior
  programming experience"

It's 12 weeks long with 10 problem sets a project.  The course includes
a taste of lots of topics that are not directly related to programming.
There is no way that anyone taking it is supposed to learn C or learn to
program during it.  The intent (as I see it) is to get a feel for what
various kinds of program look like and to "jump in" and modify some
programs in the problem sets without being any sort of expert.  It's a
though skill that's not at all the same as the methodical and
detail-oriented programming the I think many people here are more
familiar with.  I think it's it's an interesting idea.

I'm not exactly sure how the questions Alla is posting here relate to
the course (and maybe I've go the wrong CS50!) but I suspect she is
trying to understand too much.
