A static function is a function whose scope is limited to the current source file. Scope refers to the visibility of a function or variable. If the function or variable is visible outside of the current source file, it is said to have global, or external, scope. If the function or variable is not visible outside of the current source file, it is said to have local, or static, scope.
Static member functions have a class scope and they do not have access to the 'this' pointer of the class. When a member is declared as static, a static member of class, it has only one data for the entire class even though there are many objects created for the class. The main usage of static function is when the programmer wants to have a function which is accessible even when the class is not instantiated.
static function is a function in which the scope of variables are limited to that function only..i.e the variables which are declared under static function can use only with in the function as locally.and the main adv of static function is there is no need to instantiate class.
static funcn means which called itself and dere is no need of object to call static funcn.. static fun will use only static variables but not ordinary variables..
