A class defines a data type, much like a struct would be in
C. In a computer science sense, a type consists of both a
set of states and a set of operations which transition
between those states. Thus int is a type because it has both
a set of states and it has operations like i + j or i++,
etc. In exactly the same way, a class provides a set of
(usually public) operations, and a set of (usually
non-public) data bits representing the abstract values that
instances of the type can have.
You can imagine that int is a class that has member
functions called operator++, etc. (int isn't really a class,
but the basic analogy is this: a class is a type, much like
int is a type.)
Note: a C programmer can think of a class as a C struct
whose members default to private. But if that's all you
think of a class, then you probably need to experience a
personal paradigm shift.
