In short C++ objects are called "class" and may be used almost or exactly as a C struct. Largest improvement with C++ are variables within an object which fulfil similar functionality to a C struct may be private and only accessed with functions belonging to object.

Polyformism may also be an improvement there may for example be a function to move an object with different implementations depending for different object types. Polymorfism in C++ are however far as I understand not handled as in other object oriented languages, it is easy to screw things up.

I don't like C++ either but it is an improvement. I like ADA better.
