This introduces the last few points to my talk. To turn right, you can simply turn left three times. Instead of typing it out three times, however, it's easy to get the computer to count to three for you. Don't worry too much about the details unless you're interested. It's an unusual implementation that allows this counting loop to behave more like a while loop.
Variables are a vital part of programming.
They are how a computer keeps track of things, like the counting above. They can get quite complex at times, mirroring the complexity of the problem they try to solve, so it's best to consult a book, or myself to learn more about them. I hope this has been a useful introduction to C syntax, and to gives you a glimpse of the art of programming. I lean more to the software engineering side of programming than the hacking side. To me, it is more a matter of breaking up the program so that all the pieces are simple and logical than that of actual coding.
