In my thesis of the university, I also experienced with the recommendation algorithm and tried to implement some of them. It must be a fascinating topic to talk about.

I overload the new and delete operator, build it into a static library (.lib file) and require student to use this .lib file when implementing the assignment. There is no problem when building the .lib file in VS 2010 project, but there are errors when compile the source code if I link the source code to the above static .lib file.
