Chapter 19 // Exercise 12 - Principles & Practice Using C++

In this exercise I am using Visual Studio 2017 and a modified version of the std_lib_facilities header found here.

Chapter 19 // Exercise 12

I'm not sure if he wanted us to use ofstream or ifstream or even the c-style FILE. Or if he wanted us to open a file that already exists or open a new file, or use FILE to guess? I decided to go with the simple option of a file to open that already exists seeing as how FILE has not been introduced.
