Solutions to The C Programming Language, 2nd ed.

These are my personal solutions to The C Programming Language, 2nd ed. They each include a main() method that performs several tests demonstrating the efficacy of each function requested in the corresponding exercise. I have taken the liberty of adding comments to sections of code I consider somewhat incomprehensible or clever. I have also tested the limiting cases of each function, and they should all hold regardless of the maximum size of the array, defined as ARRAY_MAX.
