Create C++ class to calculate entropy and a C++ demo program - repost

I need a C++ class with three static methods. Each of the three static methods calculates the entropy of a data buffer using Renyi, Kapur, and Shannon methods of calculating entropy. Each method takes the pointer to a data buffer and the length of the buffer. Each method returns a float value with the entropy calculation. float CalcShannon( void *buffer, int nBufferLength ); float CalcRenyi( void *buffer, int nBufferLength ); float CalcKapur( void *buffer, int nBufferLength ); There must be a C++ demo program that loads and file from disk, performs the three calculations, and then displays the results. All code and projects must compile with Visual Studio 2008, 2010, or 2012. This is a repost of this project. The last person who tried to do it (SharjeelSohail) sent phony code that did not work. He also did not send a Visual Studio project. I absolutely need to have references for where the information came from.
