C++ is a fully OOP language?

Answer 1

C++ allows you to create your own types and libraries. The most important type is a class, allowing object oriented programming. A class is an abstract data type with a hidden representation and a set of public member functions and types. Classes can be organized into a hierarchy (inheritance), and you can write code that accepts any type in this hierarchy (polymorphism). Functions and classes can be parameterized by type (templated).
