How Things Work
We would be remiss if we finished this chapter without first tying a couple things together. Because the Objective-C language has the C language underneath, it’s worth mentioning some of the connections between the two. You can ignore these implementation details or use them to better understand how things work, in the same way that learning about pointers as memory addresses can help you better understand pointers. We don’t get too detailed here; we just state four facts about the relationship between Objective-C and C.
