When a variable is declared with static keyword,its called
as static variable,means it retains its value across
different function calls.Its basically used for counting no
of objects created for a class in C++ and its initialized to
0 by default.
When a function declared as static,its called as static
function.It can only operate on static variables.

Answer / zubeir
Static variable is the one allocated statically, meaning
that, it is allocated once in the program space and exists
till the program space is deallocated (the close of the
application).
Note:- Some people get confused between stack allocation
and static allocaion. Both are different terms.
A static function is again the same concept with static
variable allocation, but here the allocation is not just a
variable but a function's 'activation frame'. The
activation frame, for now, consider the function's
information required by the compiler to execute the
function which is stored internally.
