From personal experience, I learned theory and structure first. It took a long time to "get" variables as locations in memory, and I had to relearn it many times. Harvard (who sends a lot of people on to PhDs) forces everyone to learn C in introductory cs50. I like how they do it. If you don't get "the machine" early it is hard to get it later.
