Youta: Object-Oriented ANSI C

I used to know that Object Orietned programming is only available with C++/Java but not C. After thinking about it for some time, I found that it could be, I know that for C++/Java guys this doesn't look like Object Oriented programming, but lets give it a try!

The code below uses function pointers to demonstrate "instantiating" a new object, followed by performing "member functions" on the object, and then deleting the object.
