Chapter 11 // Exercise 5 - Principles & Practice Using C++

In this exercise I am using Visual Studio Community 2017 and the header file "std_lib_facilities.h" which can be found here:

Chapter 11 // Exercise 5

 Write a program that reads strings and for each string outputs the character
 classification of each character, as defined by the character classification
functions presented in section 11.6. Note that a character can have several
 classifications (e.g, x is both a letter and an alphanumeric).

This was suspiciously easy and it makes me wonder if I did it correctly.
