C++ Projects

I need a few C++ programs done. It has to be done in a few days maybe 3-4 and the work must be upstanding. What I need in this programming is the comments explaining what each string of code specifically does. Dont need any thing over the top though. If you could screen record while doing the project thats a plus and Ill through in some extra cash. Audio would be great also Program that needs to be used is Microsoft Visual C++ 2010 or 08. Below is a sample of the file BUT there will be a word document containing all of the project and instructions. I will check all the coding and making sure each string of code is explained by code as all- programmers should Software Sales A software company sells a package that retails for $99.
