6.7.5.1 Static storage duration [basic.stc.static]

All variables which do not have dynamic storage duration, do not have thread storage duration, and are not local have static storage duration.

If a variable with static storage duration has initialization or a destructor with side effects, it shall not be eliminated even if it appears to be unused, except that a class object or its copy/move may be eliminated as specified in [class.copy.elision].

The keyword static can be used to declare a local variable with static storage duration.

[ Note

:

[stmt.dcl] describes the initialization of local static variables; [basic.start.term]describes the destruction of local static variables.

The keyword static applied to a class data member in a class definition gives the data member static storage duration.
