5.6 Array-specific functions

This is NOT the latest copy of this book; click here for the latest version.

Although arrays are great by themselves, the best parts of their usefulness only come out when you use special array functions to manipulate your data - this was why we had to cover functions before arrays.

There are quite a few array functions all doing a variety of things, and you need not learn them all - your best bet is to give them all a try so that you at least know how they work, then get back to working on normal code. You'll soon learn what works for you best!
