Note that the only difference between the struct and class keywords is that by default, the member variables, member functions, and base classes of a struct are public, while in a class they are private. C++ programmers tend to call it a class if it has constructors and destructors, and the ability to enforce its own invariants; or a struct if it's just a simple collection of values, but the C++ language itself makes no distinction.
