I took classes on C in school. I never really "got it." I then re-learned C after learning Python (and other higher level languages).

I found it much easier to learn on the second try. On the first try I was learning about syntax, functions, loops, variables, and types as well as memory management, header files, and pointers. On the second try I was only learning about memory management, header files, and pointers - I already knew about the other stuff. On top of that, pointers were much easier to grasp because I had experience with 'references' in higher level languages.

It's great to learn C, but I always recommend people learn to program by way of something like Python or Ruby. It's hard to beat print "hello" when you're just starting out.
