When I first started using C++, it was still essentially a preprocessor that produced C code. I liked that because if I was really confused about a particular feature, I could examine the C code to figure out how it worked. The features that I found most interesting in C++ could be broken into two categories: Polymorphism and Encapsulation. Polymorphism is just a fancy way of saying that a given function or operation can work on different types, the way addition can be performed on both integers and floating point types.
