Simple problems resolved

Good morning!

I added the files with the solutions.
They were created in Visual Studio 2010.

Here is a print screen of the VS Solution if you want to reproduce it:

The UnitTests project needs a reference to the SimpleProblems project.

Thank you for your time.

Indeed it is much cleaner. My first time using Assert class, but i will keep in mind to use the right function based on the type of the value that is being tested.
