We went over the operator() method, which lets you treat an object like a function, and the operator[] method, which lets you treat an object like an array

We then did a bit of lab time in which students had to collectively generate tests for the next homework assignment, during which a fair bit of disagreement over how to interpret the rules took place, which is actually a pretty realistic scenario

Finally we finished with the final data structure of the class, the int.

You can treat a 32-bit int like it is 32 booleans, and insert, search, and delete individual bits in it, which allows you to pack a lot more data into the same variables, and reduce your RAM usage, network traffic, hard drive space, and so forth.
