* Author: XXXX (_INSERT_YOUR_NAME_HERE_)

* Author: Tyler Beckman
|

*
|
||||
* More complete description here...
|
||||
* A C++ program to interactively solve 10 different mathmatical equations,
|
||||
* using the appropriate constants where relevant. I decided to implement all 10
|
||||
* rather than just 2 because it sounded interesting and I wanted to challenge
|
||||
* myself. It also will keep prompting for the equation to solve until you
|
||||
* explicitly respond with a 0 or CTRL+C it, rather than just exit once the
|
||||
* equation is calculated.
