Exceptions

Get/set functions are useful, but a class consisting mostly of gets/sets is probably poorly designed: Decide whether it wants to provide an abstraction or be a

struct .

Value aggregates (also called "C-style

struct s") simply keep a bunch of data together but do not actually add significant behavior or attempt to model an abstraction and enforce invariants; they are not meant to be abstractions. Their data members should all be public because the data members

are the interface. For example,

std::pair<T,U> is used by the standard containers to aggregate two otherwise unrelated elements of type

T and

U , and

pair itself doesn't add behavior or invariants.
