/* CSCI 200: Fix Loop and Function Errors
*
* Author: Tyler Beckman
*
* Description:
* This program illustrates a variety of common loop and function
* errors. I have fixed the errors in each section.
* Note on style guide requirement: The original code used 4 spaces, so I
* reformatted most of it with clang-format.
