The struct default access type is public. A struct should
typically be used for grouping data.
The class default access type is private, and the default
mode for inheritance is private. A class should be used for
grouping data and methods that operate on that data.
In short, the convention is to use struct when the purpose
is to group data, and use classes when we require data
abstraction and, perhaps inheritance.
In C++ structures and classes are passed by value, unless
explicitly de-referenced. In other languages classes and
structures may have distinct semantics - ie. objects
(instances of classes) may be passed by reference and
structures may be passed by value.
