the static keyword when prefixed while declaring variable or function can have other effects depending on declaration occurs.

static global variable

a variable declared static @ top level of source file (outside function definitions) visible throughout file ( file scope , known internal linkage ). in usage, keyword static known access specifier .

static local variables

variables declared static inside function statically allocated, keep memory cell throughout program execution, while having same scope of visibility automatic local variables (auto , register), meaning remain local function. hence whatever values function puts static local variables during 1 call still present when function called again.

static member variables

in c++, member variables declared static inside class definitions class variables (shared between class instances, opposed instance variables).

static function

similarly, static function -- function declared static @ top level of source file (outside class definitions) -- visible throughout file ( file scope , known internal linkage ).

static method

similarly, static method -- method declared static inside class definition -- meant relevant instances of class rather specific instance.
