And there you have it. This chapter taught you all about the basic library functions that I'll be using throughout this book to make your life easier. So, to summarize, you've learned how to create large 64-bit integers, get platform-independent millisecond timers and timestamps, learned how to use strings and add functions to utilize strings better, and create an elegant and flexible log class. That's a lot of material to cover, but it's all mostly simple. Believe methis stuff will make your life so much easier later on.
