Summary
In this hour, you got your feet wet with Objective-C. You experimented a little with basic mathematics and string manipulation—the building blocks of any application. You took a look at pointers, how they work, and how they affect things like equality and comparisons. You took a look at message-passing syntax and finally spent a little time creating loops and using branching and conditional logic.
Hopefully, at this point, you are excited about Objective-C and what you might be able to do with it in the next hour, where we talk about object-oriented programming and creating and consuming your own classes.
