In Ada such a variable (not a type) is considered to contain state
information. State information is typically saved in variables in the
same package body as the subprograms that manipulate the state. In
multitasking situations (which don't arise in C++), state information is
typically saved in a protected object and manipulated by the protected
object's operations.
